Another example would be kexec. The Fedora kernel nominally supports
this feature but it requires some setup and tends to be finicky to
set up. We'd certainly take patches to fix it and we've started
to get more engaged with the kexec team to make sure it works but
ultimately it's best effort.
FWIW, recent systemd does kexec "setup"
automatically if sd-boot is used,
i.e. no setup is required, and 'systemctl kexec' should boot the same kernel
with the same options that a full reboot would.
If sd-boot is not used, some setup is necessary, alas.
