Comment # 41 on bug 909912 from Steffen Winterfeldt

I did some testing with Leap 15.1 and I don't see any timeouts at all.
Neither with LVM nor with plain device encryption.

Also, the LVM setup uses /dev/mapper/XXX in fstab already, so no change
would have been needed there.

Basically historic now, but anyway: I would have implemented variant 1
(explicit
timeout setting in config) even if it looks a bit ugly. Mainly because using
UUID=/LABEL= is quite common and it would (imho) surprise the user that
the way a devices is referred to would make a difference. While explicitly
attaching an option to LUKS devices has at least some educating value. ;-)
