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 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.
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.
--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.
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.

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.
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
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.
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
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.
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 contains simple functions for creating disk images:
mkcpio, mksquashfs, mkdosimg, mkext4img, mkbtrfsimg
And the helper functions they use:
truncate, loop_{attach,detach}, dm_{attach,detach},
mount/umount, estimate_size, roundup, cpio_copytree
