Yep, the current kernel news summaries have noticeably lacking in
prima-donna spats.  After the bit-keeper bru-ha-ha I can't think of a
single flame war.  Good for the kernel and Linux maybe,  but certainly
diminished in entertainment value. :)

Of course,  but I've never had an XFS related kernel panic.

True, and XFS in 2.5.x doesn't look anything like the xfs patches for
2.4.x.  2.5.x has moved journaling, extended attributes, etc.. all into
the VFS.  It will be interesting to see how well it all plays out.

It is, SGI is legendary for that.  It would be nice if they'd release
some of their techniques.  But then their techniques may be pretty
obsolete at this point.

The article writer seems to like IRIX, most admins I've talked to who
have had to live with them regard it as the bastard UNIX plagued with
stability and security problems.  It is liked even less than AIX!  And
AIX is easy to hate, except for the fact that it just flat out never
crashes.
