I like to play with development software, I guess I have a masochistic
nature :) Thank you for your advice, though.

It's not long since I installed this system, and almost all
customizations are under /home, which is on a separate SSD, so it's
easy to preserve that. I guess I could do an apt-clone before
upgrading, so that if something goes wrong I can just reinstall and
apply the archive that apt-clone makes. Or is there a better way of
quickly getting a system back to a set state?

The separate partition idea is good, though. If the upgrade fails in a
spectacular way, then I will probably split the space on the boot SSD in
half for future experiments :)

Thanks again, I will try out the upgrade procedure.
