Well, it was both.  I should have written "feedback" instead of "rant."

I really don't care which filesystem they choose.  If they decided to
extend vfat to the point where it supported the features required for me
to get my job done, I'd use it.  The point is that there is an important
feature, readily available, that they aren't supporting for whatever
reason.   Perhaps it's because they don't know how much easier an
admin's life is with it, hence my feedback.

The ext3 online extend code been around for a couple years.  When I made
the decision to go with reiserfs/LVM on Redhat 7.3 in 2001, I looked at
the ext3 patches for 2.2/2.4 and decided to go with something that is
already in-kernel and actually deployed on production servers (SuSE has
been supporting this for a while).  I mainly ask for another filesystem
because the above patch doesn't have the level of testing that reiserfs
has.  I can't say from personal experience how well XFS or JFS supports
online extention.

Obviously.  I ask on the beta list because this is something, as a
sysadmin, that I feel an "Enterprise" product should support.  On my
other unix servers (HP-UX), this just works (Veritas VXFS), but I don't
have to go out of my way (or support contract) to get it.  It's
default.  I could purchase VXFS, but why should that be necessary when
there are three filesystems in Linux that already do this.
