I've used it from the days when it was the only journaled fs around
and an fsck of the stock e2fs drives cause hours of downtime
after any crash and have not had any more problems with it than
any other fs type.   The one thing you might have to be careful
about is that there have been different versions and the
tools need to match the filesystem version.  But you see the
same thing with ext3 on Linux. You can't, for example create
ext3 filesystems on a current version, restore an old system
on them, and have it come up working even though both claim
to be ext3.

I don't think I'd install the OS on it - just create new
filesystems afterwords and move /home and /var onto them.
