No, because the preinst is also run in the middle of the upgrade and causes
the upgrade overall to fail.

If you detect multiple ESPs, how do you decide which one to mount?

(It's possible that yes, we could work this out based on things like current
efibootmgr settings, but I think it would be somewhat error prone and you
would still want to detect it all before starting the dist-upgrade.)

blkid -t PARTUUID=$(efibootmgr -v | awk '/^Boot..... ubuntu\t/ { print $NF }' | cut -f3 -d,)
