That's true, but I very recently (last week) built a gfs2_edit
program that runs on RHEL4.6.  (Yes, I know gfs2 won't run on
4.X but the gfs2_edit tool can still be used to work on gfs1
file systems.)

I'm trying to get a people page worked out, and if that
goes through, I'll post it there.  I can send a tar/zip version of
the source tree for this if anyone wants it.  It's basically the
same cluster source tree as 5.2, but I've modified it slightly so
that it will compile on 4.6 without too much hassle.
I can also easily send a x86_64 binary for RHEL4.6 gfs2_edit if that
helps.  A 32-bit version would be hard for me to build at the moment.

The original gfs_edit is pretty primitive compared to gfs2_edit.
