I'm working on
https://fedoraproject.org/wiki/Changes/WorkstationOstree and when
using lorax to make an installer ISO with content embedded, I run out
of disk space since the desktop+various apps is large.
Since this ends up being compressed anyways, let's just bump the
currently arbitrary `2` to `10` - the only real cost I can think of is
going to be a few more superblock entries.
If the query filter doesn't return anything it would just ignore the
install request instead of logging and raising an error when
required=True.
This checks for no packages matching, and if required is True raises an
error after all of the requested packages have been processed, instead
of after the first one to fail.
Previous versions of lorax assumed that installpkg was optional, and
would continue on if the PKGGLOB didn't match anything. But the majority
of the packages are required so this allows the boot.iso to be built
with missing packages that are hard to track down.
It makes more sense to make the PKGGLOB required and to flag the
few exceptions to this with --optional.
Fedora now has a edk2 package so use the OVMF code from there. This also
adds using a copy of OVMF_VARS for each boot instead of reusing the one
provided by the package.
There's no reason to require the initramfs when we can rebuild it using
the version from the kernel. This adds handling of missing initramfs so
that lmc kickstarts can remove it from the squashfs, saving about 40M on
the iso.
umount tries to delete a mountpoint if it has lorax.imgutils in the
path. This doesn't work right if you try to umount something mounted
deeper on the path.
This adds a delete option, which is True by default, to skip the delete.
When using the template install command copying the same file to itself
shouldn't crash. Just log the error and continue.
Also copy the s390 configuration files for use with livemedia-creator
Resolves: rhbz#1269213
Allow the template to select a different compression type or arguments
for the installimg command.
On 32bit builds running inside a mock xz sees the full amount of system
memory which can result in xz failing with a memory error. This allows
the template to limit the amount of memory it tries to use.
If there isn't enough space for DNF to download packages it will log:
"Not enough disk space to download the packages."
So add this to the messages in monitor that trigger an error.
This makes package selection a little more roundabout, but it allows for
unused packages (and their dependencies) to be removed from globs during
the install phase.
dnf.subject.Subject is the class used by dnf's Base.install to select
packages, so the behavior of installpkg without --except options is the
same as it was before.
When using no-virt the runtime filesystem size comes from the kickstart.
For virt installs lmc was creating a runtime filesystem that was just
slightly larger than the space used by the files installed by anaconda.
This can run into problems with larger filesystem. It is also
inconsistent behavior between virt and no-virt installations.
With this commit the virt runtime filesystem will also come from the
kickstart.
This allows lorax to support multiple templates.
If there is no templates.d under the sharedir (/usr/share/lorax or the
directory passed by --sharedir) then the templates in that directory
will be used as they were previously.
If there are directories under templates.d the first one will be used,
unless --sharedir points to a specific one.
Use 4k blocks for the ext4 filesystem. Run fsck on the filesystem to
make sure deleted blocks are actually zeroed, and pass -Xbcj to
mksquashfs.
4k blocks and -Xbcj decreases the size by 2-6% depending on the
filesystem size. Zeroing the blocks of the ext4 fs improves things
dramatically. The problem is that DNF downloads the rpms before
installing them. In addition to forcing us to use a larger filesystem
than we would like it leaves data that is difficult to compress on the
image. The downloaded files are removed, but need to be zeroed out so
that mksquashfs can compress it.
Sometimes debugging a boot.iso requires using gdb, and finding the
corresponding debuginfo packages can be difficult. This writes the
matching -debuginfo package names and full ENVR to a file on the iso.
This can then be fed to dnf to install the correct debug packages.
Sometimes you don't want to include the selinux xattrs in the tar (eg.
bsdtar has problems extracting them). They are still included by
default, but pass selinux=False to remove '--selinux --acls --xattrs'
from the tar cmdline.
This allows the partition to be mounted on a directory underneath the
temporary directory, eg. /rootfs/, to help support creating other image
types without needed to move the files around.
When running the transaction in a separate process it crashes if you use
a https repo source. There's really no need for threads or processes in
lorax so drop it.
Also switched to using the DNF TransactionProgress API for progress
reporting.
The system the image boots on will likely not match the host where lorax
was run, and in some cases this can cause systems to hang.
Resolves: rhbz#1258498
fedup is deprecated and abandoned. Let's save time and disk by not
building `upgrade.img` when nothing is going to use it anymore.
For the record, performing upgrades using an initramfs from the new
system turns out to be fragile and hard to support:
* dracut initramfs isn't generic enough to handle booting all systems
(e.g. missing vconsole.conf means you get keymaps wrong, so users
can't unlock encrypted disks)
* The ABI differences between the two versions of plymouth, systemd,
etc. requires nasty workarounds at best and causes nightmarish
systemd crashes at worst
This patch removes all the code that built and installed `upgrade.img`.
For backwards compatibility, the API retains the `doupgrade` keyword
argument, and the `--noupgrade` flag is still accepted.
Some callers expect CalledProcessError.output to have the output, so
pass up the stdout + stderr output.
This means failed runcmd template commands will log to program.log and
lorax.log
After the cleanup step, check that everything in /usr/bin and /usr/sbin
can still run. Currently, this just checks that ELF files have
everything they need to link, and scripts have an interpreter.
Verifying is on by default but can be skipped with --noverify
When this is too small the rootfs can run into problems when used with a
live system. Doubling it leaves enough space for the system to run
properly during the installation and since it's all compresses it
doesn't make the image noticeably bigger.
Add a 'lower' filter to the templates to replace string.lower which no
longer exists. Fix udev_escape, the strings are already unicode, and
drop --chdir from runcmd. It wasn't ever used, and passing cwd to the
new runcmd isn't supported.
Fix up 2to3 complaints. I've decided to do with wrapping list
comprehension inside list() to get the generators to run in several
places instead of list(map( or list(filter( which seem less readable to
me.
If it terminates really badly (e.g. with SIGSEGV), it doesn't report any error,
just doesn't put anything to the queue. So instead of just blindly waiting on
the queue forever, check that the process is still alive if we don't get any
message in long time interval.
I originally added --add-template to support doing something similar
to pungi, which injects content into the system to be used by default.
However, this causes the content to be part of the squashfs, which
means PXE installations have to download significantly more data that
they may not need (if they actually want to pull the tree data from
the network, which is not an unusual case).
What I actually need is to be able to modify *both* the runtime image
and the arch-specific content. For the runtime, I need to change
/usr/share/anaconda/interactive-defaults.ks to point to the new
content. (Although, potentially we could patch Anaconda itself to
auto-detect an ostree repository configured in disk image, similar to
what it does for yum repositories)
For the arch-specfic image, I want to drop my content into the ISO
root.
So this patch adds --add-arch-template and --add-arch-template-var
in order to do the latter, while preserving the --add-template
to affect the runtime image.
Further, the templates will automatically graft in a directory named
"iso-graft/" from the working directory (if it exists).
(I suggest that external templates create a subdirectory named
"content" to avoid clashes with any future lorax work)
Thus, this will be used by the Atomic Host lorax templates to inject
content/repo, but could be used by e.g. pungi to add content/rpms as
well.
I tried to avoid code deduplication by creating a new template for the
product.img bits and this, but that broke because the parent boot.iso
code needs access to the `${imggraft}` variable. I think a real fix
here would involve turning the product.img, content/, *and* boot.iso
into a new template.

This can be used to remove kernel modules from under
/lib/modules/*/kernel/ while keeping specific items. This should be
easier than constructing find arguments to select the right things to
save.
It appears that reset+fill_sack will now do the right thing and load the
state of the installed packages. Drop the hack with deleting the object.
Also add a double-check to make sure there really is a list of files
for anaconda-core before we run off and make an image without removing
anything.
This is a workaround for a current dnf bug, it doesn't update the state
of the packages after they are installed so we tear down the base dnf
object and create a new one pointing to the installroot.
There is an additional issue with the list of files returned, hawkey and
dnf don't appear to make a distinction between files, dirs and ghosted
dirs like yum did, this can result in too much being removed (eg. all of
/etc/selinux/) so we only remove files not directories.
pylorax users will need to change to using dnf and pass a dnf.Base()
object as the dbo argument instead of a yum object as the yum or ybo
argument. See the lorax script for an example of how to do this.
The lorax cmdline argument --excludepkgs has been removed since dnf
doesn't appear to have any way to support it and packages should be
controlled using templates anyway.
--make-pxe-live target generate live squashfs and initrd for pxe boot.
Also generates pxe config template.
--make-ostree-live is used for installations of Atomic Host. Additionally to
--make-pxe-live it ensures using deployment root instead of physical root of
installed disk image where needed. Atomic installation needs to be virt
installation with /boot on separate partition (the only way supported by
Anaconda currently). Content of boot partition is added to live root fs so that
ostree can find deployment by boot configuration.
Previously if there was an error during a novirt installation that
didn't exit the process there was no way to detect it. This uses the new
--remotelog option for anaconda to monitor the logs for errors using the
same criteria as it does when monitoring a virt install. If there is an
error the anaconda process will be terminated and the logs will be
gathered up into ./anaconda/
Recently, Fedora has been trying to do a 3 product split. As part of
that, lorax was changed to do "installpkg lorax-product-*" via
provides.
I think that approach is awkward; a much simpler approach is to simply
specify the product package as input to lorax on the command line, via
external rel-eng scripts.
This patch therefore adds --includepkg (and we should probably add an
option to remove the implicit lorax-product-* glob).
installimg SRCDIR DESTFILE
Create a compressed cpio archive of the contents of SRCDIR and place
it in DESTFILE.
If SRCDIR doesn't exist or is empty nothing is created.
Examples:
installimg ${LORAXDIR}/product/ images/product.img
tar recurses into directories by default, but find is feeding it all the
files and directories so the tar it produces is considerably larger than
it needs to be due to duplicate files. Add --no-recursion flag so that
tar will only add the specific files and directories piped to it by find.

The 32MiB size limit does not apply to upgrade.img since it's installed
to /boot by redhat-upgrade-tool instead of downloaded through TFTP. The
warning in rebuild_initrds will still be triggered by an upgrade.img
over the limit, but this doesn't halt the compose and it's probably not
a bad thing to know about.
Spaces cause various bugs like #923374 and #855849 , and it would be
better if we just didn't use them.
Note that there's a corresponding pungi change to go with this.

What I need is to make something like the traditional DVD which also
includes packages. At present this is apparently handled by the
entirely separate pungi tool.
At the moment for me, it's the least bad option to modify lorax to
inject data from an external source than to create a new tool, or
attempt to also modify pungi to do this.
This would also allow pungi's DVD creation to eventually be a set of
external templates for Lorax.
Commit d2ae92b4b3 patched up the download counter and progress
display. Yum no longer provides the needed information so now we get the
total number of packages from the start of the transaction.
This also turns off colors when stdout is not a tty, and only prints the
install progress once so that piping to a logfile isn't flooded with
useless characters.
This adds the --make-tar option which will produce a xz compressed tar
of the root filesystem. This works with either virt-install or no-virt
modes. Use --image-name to set the output filename.
--compression is used to set the compression type to use, which defaults
to xz. Supported types are xz, lzma, gzip and bzip2.
--compress-arg is used to pass arguments to the compression utility.
Remove more drivers and remove plymouth and drm dracut modules. Only on
PPC64 initrd, all other arches have the full set of drivers and modules.

Make sure the data is written before we do anything else with the disk
image. This shouldn't be needed, umount should take care of it, but it
also can't hurt.
Resolves: rhbz#1052175
Fix "lorax -V" and add a "version is ???" to the log file so we can easily know
what version of lorax is used to build an iso.
Changed to try/import for versioning because the version file is autogenerated.
We should probably let the user know if something goes wrong with the
transaction or if a scriptlet fails. So: log the messages so we can find
(and, one hopes, fix) them later.
Some package scripts may call utilities using dbus. Since this is just a
chroot that will fail. This unsets DESKTOP and DBUS_SESSION_BUS_ADDRESS
to keep them from crashing.
It used to give us (x/y) packagename, but now it only sends package
name. This was changed in yum commit 7e8c76173. For now default to
showing the zeros along with the package name so that it doesn't look
like an error.
kpartx can return before the devices are created. Use -s to wait.
Also remove -p p and let kpartx handle adding pX if needed, we use
whatever it outputs so there is no need to force a name.
This makes findkernels() look for any image named something like:
$PREFIX-$KERNELVER.img
and adds a corresponding entry to its returned data like:
kernel.$PREFIX.path = [path]
As a special backwards-compatibility case we use 'initrd' for the
attribute name if $PREFIX is 'initramfs'.
This gives us any extra initramfs images that may have been built using
the 'prefix' argument to rebuild_initrds().
If 'prefix' is passed to rebuild_initrds(), it will build a *new*
initramfs with a name like $PREFIX-$KERNELVER.img, rather than
overwriting the existing initramfs.
Dracut now makes the initrd with 600 permissions
for security reasons. These reasons do not apply
to install images, and we want the other tools
that use lorax to be able to read the initrd file.
When I switched execution over to execWith* functions I failed to
account for the use of CalledProcessError in various places. This
patch restores that behavior. All places that used check_call or
check_output now pass raise_err=True to the execWith* call.
Switch to using execWith* so that the command and its output can be
logged. To capture the output setup a logger named "program"
livemedia-creator captures all of this into program.log
The 'systemctl' command can be used to enable, disable, or mask systemd
units inside the runtime being modified. Modify runtime-postinstall.tmpl
to use the 'systemctl' command.
We also no longer remove quota*.service or kexec*.service, since
these aren't enabled by default. And systemd-remount-api-vfs.service
should work correctly now, so we can leave it alone as well.
The '-cmd' functionality depends on the individual lorax template
commands raising errors, so they shouldn't do sys.exit().
Also, capture stderr along with stdout, and put both in the log.
There's something strange going on where unmounting a hfsplus volume
immediately after mounting it will fail with EBUSY.
This makes the umount fail, which makes the rmdir fail, which causes a
traceback, which breaks mkefiboot --apple.
It works fine if you wait a second and retry.. so do that.
Also, add the "lazy" argument so you can do lazy unmounts if you like.
Generally it's not a good idea for python libraries to set up loggers in
the body of the library.
Set up a NullHandler by default (as the logging module suggests), and
add a function to do the current logging setup during run().
From Harald Hoyer <harald@redhat.com>:
pollcdrom is used to poll for the install medium. A lot of CDROM drives
are not polled by the kernel correctly, so we have to actively poll for
the medium.
Some packages are critical to the compose. If --required
is specified in the template's installpkg command, lorax
will exit if the package is not available.
Mac boot images are optional. Don't require hfsplus-tools
by default, but warn the user that he needs to install them
if he wants to create mac boot images.
Install the anaconda dracut module during 'install', use it when
rebuilding initramfs, and clean it up afterward.
Also install '.buildstamp' into the initramfs (the anconda module wants
it).
Fedora 17 changes top level directories like /bin, /lib, etc. to
symlinks to the corresponding dirs in /usr/
dracut can convert old systems to the new layout using its convertfs
module.
The installer no longer has access to the initrd's root. We need to
copy any needed files over to /sysroot before switching root. This
copies *.cfg and *.ks files.
It also adds the ability to add dracut hook scripts to the initramfs
from /usr/share/lorax/dracut_hooks/
This re-adds commit af6d4e2c50 which was
lost during the switch to the treebuilder branch.
