Same as $KERNEL_INSTALL_BYPASS, but for hwdb. This will speed up
cross architecture image builds in mkosi as I can disable package
managers from running the costly hwdb update stuff in qemu user
mode and run it myself with a native systemd-hwdb with --root=.
Now that mkosi-kernel is a thing, this logic in systemd is just mostly
bitrotting since I just use mkosi-kernel these days. If I ever need to
hack on systemd and the kernel in tandem, I'll just add support for
building systemd to mkosi-kernel instead, so let's drop the support for
building a custom kernel in systemd's mkosi configuration.
This code doesn't link when gcc+lld is used:
$ LDFLAGS=-fuse-ld=lld meson setup build-lld && ninja -C build-lld udevadm
...
ld.lld: error: src/shared/libsystemd-shared-255.a(libsystemd-shared-255.a.p/cryptsetup-util.c.o):
symbol crypt_token_external_path@@ has undefined version
collect2: error: ld returned 1 exit status
As a work-around, restrict it to developer mode.
Closes https://github.com/systemd/systemd/issues/30218.
- Use mkosi.images/ instead of mkosi.presets/
- Use the .chroot suffix to run scripts in the image
- Use BuildSources= match for the kernel build
- Move 10-systemd.conf to mkosi.conf and rely on mkosi.local.conf
for local configuration
don't let the devices to be announced just as model "Linux". Let's instead
propagate the underlying block device's model. Also do something
reasonably smart for the serial and firmware version fields.
Introduce a new env variable $SYSTEMD_NSPAWN_CHECK_OS_RELEASE, that can
be used to disable the os-release check for bootable OS trees. Useful
when trying to boot a container with empty /etc/ and bind-mounted /usr/.
Resolves: #29185
I tried to get something similar upstream:
https://gitlab.com/cryptsetup/cryptsetup/-/issues/846
But no luck, it was suggested I use ELF interposition instead. Hence,
let's do so (but not via ugly LD_PRELOAD, but simply by overriding the
relevant symbol natively in our own code).
This makes debugging tokens a ton easier.
Automatically softreboot if the nextroot has been set up with an OS
tree, or automatically kexec if a kernel has been loaded with kexec
--load.
Add SYSTEMCTL_SKIP_AUTO_KEXEC and SYSTEMCTL_SKIP_AUTO_SOFT_REBOOT to
skip the automated switchover.
