Public bug reported:
I'm not quite sure if this is the right category so excuse me, if I'm
wrong here.
I've installed Ubuntu 21.10 using the latest installer. During the
installation I've enabled zfs and encryption. The installer created a
/etc/crypttab file that looks like this:
cryptoswap /dev/sda2 /dev/urandom swap,initramfs
This is really bad because the disk behind /dev/sda may change and
unfortunately did change in my case. This can lead to data lost on other
disks.
I would suggest to use the UUID instead of "/dev/sda2".
