Robust filesystem for power failures

We use Reiser for nonroot partitions, and like it. We wish it were more liked by kernel devs. But it does have power failure issues, if the article is right. Try ext3.
Another help against crashes is to move the admin user to a separate /home partition, so you end up with /home/root, /home/user1, /home/user2, etc. Backup and restore of /home partitions is easy.
System partition rescue/recovery/rebuild can be done by grml-live-cd or grml2hd independent of /home partition.
Current grml does not permit moving the admin user. It's on the wishlist.

That's just not true.
cp -a /root /home/ mv /root /root.old ln -s /home/root /root

cp -a /root /home/ mv /root /root.old ln -s /home/root /root
A symlink hack may work. The right way to change user accounts is useradd, usermod, adduser, etc. Try changing admin's HOME with those. At one point grml gave me a message
"No directory, logging in with HOME=/"
even though still using /root as usual.
Thanks grml team, you're the best, M.

Strange. I cannot reproduce it, but I found a possible racecondition in zshenv (necessary for live-cd mode) and will double check that. Thx.

Wow, thanks a lot for the info.
I shifted from ext3 to Reiser because ext3 would take 10 times more time to recover, and sometimes the recover would fail. Now I know why -- because it *is* a serious job...
thanks a gain
