Before this commit, if `original_path` is given,
it will always be used to overwrite `path`.
After this commit, it's controlled by the newly-added
switch `overwrite_with_origin`.
This also migrates the configuration to the new format that was
just merged in mkosi. Specifically, we make use of the new [Match]
sections to only include specific config snippets per distro.
When adding a sysext image to the system and manuall merging it, a
later "systemctl (re)start systemd-sysext" won't work because "merge"
refuses to work when something is merged already. Another problem with
"merge" at start plus "unmerge" at stop is that a service restart can't
make use of the new MOVE_MOUNT_BENEATH in the future even which would
only be available in "refresh". It also prepares us for setting up the
merged overlay for the sysroot from the initrd already, which also
would lead to the mentioned start problem of the service (One
optimization could be to skip the loading but only if we are sure that
all images were loaded and weren't modified since - this assumption is
hard because early services could want to inject a sysext, too).
Use "refresh" on service start to fix the problem that the service
can't start as soon as a manual merge was done. Also add a reload
action that allows to issue "systemctl reload systemd-sysext" and it
will make use of MOVE_MOUNT_BENEATH once we implement this in
systemd-sysext refresh (and it's available from the kernel).
The /usr/lib/extensions/ location for systemd-sysext images is not
supported anymore. In https://github.com/systemd/systemd/pull/26013
systemd-confext images got introduced and we can list its path under
/usr instead.
With certain fstabs we may propagate ENXIO from the $SYSTEMD_SYSFS_CHECK
check all the way up, making fstab-generator exit with a non-zero EC and
without any helpful message, which is really confusing.
The confext concept is an extension of the existing sysext concept and
allows to extend the host's filesystem or a unit's filesystem with signed
images that add new files to the /etc/ directory using OverlayFS.
The release file that accompanies the confext images needs to be
host compatible to be able to be merged into the host /etc/ directory.
This commit checks for version compatibility between the image file and
the host file.
Adds a new image type called IMAGE_CONFEXT which is similar to IMAGE_SYSEXT but works
for the /etc/ directory instead of /usr/ and /opt/. This commit also adds the ability to
parse the release file that is present with the confext image in /etc/confext-release.d/
directory.
If we don't find a single useful partition table, refusing dissection.
(Except in systemd-dissect, when we are supposed to show DDI
information, in that case allow this to run and show general DDI
information, i.e. size, UUID and name at least)
This allows unprivileged validation of DDIs. Only superficial structure,
i.e. not mounting or so. This becomes particularly handy in the
integration tests, and to validate image policies.
This is to dissect_image_file() what dissect_loop_device_and_warn() is
to dissect_loop_device(), i.e. it dissects the image file and logs an
error string if that fails instead of just returning an error.
- Remove useless serial console configs
- Add CONFIG_SERIAL_8250_PCI so that qemu's virtconsole works properly
- Add CONFIG_DMI and CONFIG_DMI_SYSFS so that SMBIOS credentials work
- Add CONFIG_IKCONFIG and CONFIG_IKCONFIG_PROC so we can read the
current kernel config from /proc/config.gz
- Add CONFIG_IOSCHED_BFQ to get rid of a udev error on boot on Fedora
- Add CONFIG_HW_RANDOM_VIRTIO to get hw rng in qemu
- Add CONFIG_SECURITY_YAMA to get rid of warning from sysctl on boot
- Add CONFIG_VSOCKETS and CONFIG_VIRTIO_VSOCKETS to enable vsock support
