Support analyzing ostree repositories or directory that contain an
ostree commit as created by osbuild. Will return the mode of the
repository along with the references and their commits. For the
first references, the commit is resolved and checked-out to a temp
directory. This directory in turn is then analyzed via the existing
append_filesystem function. The latter has gained some small ostree
specific tweaks.
NB: for the ostree checkout /usr/etc/ is bind mounted to /etc in
order to make append_filesystem happy. The rpm verification step
is NOT run, because that is not really compatible with ostree.
Move the code of the current main into is own method and call that
from main. This prepares support for analyzing other types than
images. Additionally, add argument parsing via argparse to get a
help texts.
systemctl list-unit-files doesn't produce machine readable output.
parse_unit_files isn't very good at reading it and can produce duplicate
records.
This commit fixes it by deduplicating and sorting the units. This is a bit
hacky solution, but should work just alright. In the future we might
dump list-unit-files and do the job ourself, but let's not recreate the
systemd logic for now.
If we detect a ESP (via its type UUID) remember it and mount it at
any filesystem that has a /boot/efi (there should in theory be
only one). This is needed so grubenv can be read, which is likely
a link from /boot/grub2/grubenv to ../efi/EFI/$vendor/grubenv.
Additionally this will make rpm verify not report that all the efi
binaries are missing, e.g.:
"missing": [
"/boot/efi/EFI",
"/boot/efi/EFI/BOOT",
"/boot/efi/EFI/BOOT/BOOTIA32.EFI",
"/boot/efi/EFI/BOOT/BOOTX64.EFI",
"/boot/efi/EFI/BOOT/fbia32.efi",
"/boot/efi/EFI/BOOT/fbx64.efi",
"/boot/efi/EFI/fedora",
"/boot/efi/EFI/fedora",
...
This shows the changes an image has relative to what its rpm database
thinks is installed. Output is:
"rpm-verify": {
"missing": [ <missing files> ],
"changed": { <map from filename to rpm attribute octet > }
}
Alas, this makes running image-info slower.
For each partition, find out if its the root or boot partition and
gather only the relevant information. Make sure that we don't get
information from /boot twice.
Rough draft of image-info, a tool that extracts high-level information
about an os image. It prints this information in JSON form on stdout.
Run it like this:
$ tools/image-info <image>
It supports all images that qemu-ndb supports.
