Erhm...  It seems to work sort-of well enough for me, but I haven't
done snapshots for quite a while.  What I miss the most is pvmove,
that is severely broken ;-(  I guess I'll keep on using LVM1 on-disk
format and keep a FC1 rescue CD handy for cases in which I need
pvmove :-/

Most likely when it's integrated in the upstream kernel, and probably
only for FC3, unless there's good reason for major kernel updates for
FC2.  LVM support might be it, but I wouldn't count on that.

Well, if's Free Software, there's always hope :-)
(as long as you don't end up with proprietary undocumented hardware :-)

/me hands the `thank you' to those who actually make it happen.

I'm just a random Fedora user that happens to have an @redhat.com
e-mail address :-)
