AMI images are un-partitioned filesystem images with a grub.conf that
is read by the pv-grub bootloader used by EC2. Most of the actual work
making the AMI is done in the kickstart. This just creates the image
file.
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.
In the latest method for booting the rootfs is in the LiveOS
directory of the media, not appended to the initrd. Detect this
and mount the iso and pass the CDLABEL to virt-install.
Some repos may contain anaconda packages for more architectures,
so it's not possible to get the right buildarch.
This patch allows optional specifying of the buildarch on the
command line when running lorax.
If the buildarch is not specified manually, lorax tries to get
it from the anaconda package as before.
If there's no anaconda package in the repository, don't fallback
to the system architecture and continue, because this is pointless.
We need the anaconda package.
When considering a package's filelist (e.g. for things like removefrom
--allbut), we might need to also include the %ghost files, so make
_filelist() add them to its returned list.
This runs anaconda directly, using the --image install feature. The host
system should be the same release as the target system in order to avoid
unexpected problems.
livemedia-creator uses an anaconda install media iso to install to a
file image. virt-install is used to execute the kickstart. lorax is used
to post-process the image file and create a bootable .iso from it.
Future additions will allow creation of EC2 images and output xml
details about the install.
The anaconda execWithRedirect and execWithCapture functions are too
useful not to include. They also allow you to log all the execuatable's
output to a logfile. Added them under executils.py module which uses
the pylorax and a new program logger.
Allow passing of size to create_runtime, add PartitionMount context
to use kpartx to mount partitioned file images. Add resetting the
selinux context on the newly created rootfs.
This means that any (non-ignored) command error will cause lorax to
exit.
Do note, however, that some commands (e.g. remove, installpkg) don't
raise exceptions and therefore will not cause lorax to exit.
Makefile-style "-cmd" syntax lets us run a command and ignore any
resulting errors. This is a more general version of what copyif/moveif
were trying to accomplish, so we can drop those commands.
New images find their root device by looking at the CDLABEL. Since pungi
is building ISO images separately from lorax, if it uses a different ISO
Volume Label we'll end up with unbootable images.
This changes the volume labels to match what pungi uses, so both should
boot OK.
- Log the error message (and the line causing the error) to console
- Log the whole exception (with some excess junk removed) to debuglog
- don't immediately SystemExit if the template won't parse
- clean up some comments
This lets us easily do whitelisting instead of blacklisting during
runtime cleanup. For example:
removefrom xfsprogs --allbut /sbin/* /usr/sbin/xfs_admin
would remove everything from the xfsprogs package except files in /sbin
and /usr/sbin/xfs_admin.
A few things in runtime-cleanup have been converted to use --allbut. The
only difference in the created runtime image is that we're deleting
/usr/share/kde4 from fedora-logos.
