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
