Roger, you're welcome to flatter me any time ;-> , but, really, I 
tend to be years behind the times in tricks used on my servers.  Partly,
that's because I'm a coward and want to benefit from other people's
experience, rather than be a pioneer.  Also, the last half-decade my
hardware's been so trailing edge that some new features didn't seem to
have much point (e.g., 2.6 kernels' SMP improvements weren't much use on
my aging single-proc systems).

Partitioning, in any event, is an extremely debatable topic that people
have a huge range of views on.  A few principles are settled matters,
but there are many things that involve guestimates and SWAGs.

Anyhow, thank you, and I'm definitely reading up rapidly on these
topics.  In fact, I think I'm about ready to build this sucker.   Here's
the revised filesystem layout, taking into account some excellent
suggestions from the SVLUG mailing list.  (This is almost /etc/fstab
format, except for the extraneous "Size" column that's present for
reference -- and except for the bracketed stuff.)

Filesystem  Size  Mounted on  FStype  Options                     Dump  Pass

Reminder to myself: Check supplies for more compatible SDRAM sticks.

Please remind me to post a few things about this, later.
