Public bug reported:
Using the server install ISO, it's possible to specify root on LUKS and
variations thereof - for instance, root on LUKS on MD-RAID, root on LVM
on LUKS on MD-RAID, and so forth. The installer does the right thing and
initramfs-tools does everything necessary to support booting this sort
of thing.
However, systemd gives a 90-second timeout on restart or shutdown,
presumably because it cannot dispose of the things beneath root.
It's wholly unclear to me where the 90-second timeout is specified,
should I wish to shorten it to reboot without the futile delay, but more
to the point, there seems to be infrastructure for handling this kind of
situation that doesn't exist in Ubuntu at present.
I was pointed at this:
https://www.freedesktop.org/wiki/Software/systemd/InitrdInterface/
However, Ubuntu seems not to have anything in its initramfs-tools to
facilitate "shutdown-initrd" functionality.
I haven't tested this, but I suspect this problem will exist for folks
running root on MD-RAID without the LUKS as well. Either way, a
relatively common vanilla install will force 90-second timeouts on
users, which is unfortunate.
