IMO, better to use Debian or Slackware.  I went through "RPM Hell" back
in the days when I ran S.u.S.E. (complete with full-stops in the name)
and I will never go back.

Watch this space.  You might read something to your advantage in the
next few days.

Well, /boot cannot be on LVM, as the BIOS does not know about logical
volumes.

It's no worse than a normal partitioning system, just more flexible.
[Of course, that also means that it is more flexible for you to destroy
your DASD farm yourself.]

Same as partitions: just keep backups.

I have some scripts that generate LVM rebuild scripts.  These scan the
current logical volumes and generate lvcreate commands into a script
that can rebuild your LVM set-up in seconds.  You (or anybody else) are
welcome to a copy if you wish.

After that, back up the contents using tar, dar, cpio or whatever your
favourite archiving tool happens to be.
