There isn't a more current version, no.  I guess (for the moment anyway)
I maintain it, since I was the one that took the original and added the
config file, support for other filesystems, etc.  (All that really
happened was some discussion on the ext3-users list.)

If you have patches, I'd be happy to apply them, and re-post.  :-)

(I did try running it once or twice, but those were older versions, and
lots of stuff got changed since then.  Unfortunately my main system
doesn't use LVM, and the qemu image that does seems to be corrupted (it
crashed at one point, and the RAID5 under the LVM got screwed up), so
it's been a long time since I ran it.  It sounds like I should create
another qemu image and start testing it again.)

Ouch.  I don't remember exactly when that part of the script changed,
but obviously it should be using -L, and should have an "M" suffix.
I've fixed that.

If there are any other users.  ;-)

So far, this is just an idea that was brought up in the context of ext3
(and someone complaining about really long fsck times being forced on
them on huge FSes).  I brought it up here in an attempt to get it maybe
merged into the LVM tools.
