I wish I had checked this earlier. I did a combined upgrade ubuntu
16.04->18.04 and 0.28->0.29 on a BE and separate FE this week.

As usual, I did a backup of the database first, then upgraded from
0.28->0.29, then upgraded the release.

Both systems are on lvm on top of raid, so I simply mirrored the root lv
at each step. That way, if the system borked completely or partially, I
would be able to mount the needed mirror volume and/or boot from it. I
do this at every dist-upgrade, in fact, because sometimes the system
gets broken...or a script overwrites/deletes something that you actually
wanted to keep...

Anyhow, this time, everything worked fine (except ffmpeg, but that is
another can of worms...)

I relate all this because clonezilla and co. seem very inflexible. It
would be better to have a strategy for dealing with updates/upgrades in
a seamless way. Of course, filesystems like zfs might be an even better
option but I haven't been brave enough for that.
