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
/dev/sda1 200M /boot ext2 nodev,nosuid,noexec 0 2
/dev/sda6 500M [swap] [swap] sw,pri=1 0 0
/dev/sda8 6000M /var ext2 noatime,nodev,nosuid 0 2
/dev/sda9 1000M / ext3 defaults,errors=remount-ro 0 1
/dev/sda10 1000M [recovery] ext3 rw,noauto 0 2
/dev/sda11 5000M /usr ext2 nodev,ro 0 2
[rest of sda unallocated, for now]
/dev/md0 2000M /var/www ext3 nodev,nosuid 0 2
/dev/md1 1500M /var/lib ext3 nodev 0 2
/dev/md2 3000M /var/spool ext3 noatime,nodev,nosuid 0 2
/dev/md3 500M [swap] [swap] sw,pri=2 0 0
/dev/md4 6000M /home ext3 nodev,nosuid 0 2
/dev/md5 5000M /usr/local ext3 defaults 0 2
/dev/fd0 /media/floppy auto rw,user,noauto 0 0
/dev/hda /media/cdrom iso9660 ro,user,noauto 0 0
tmpfs /tmp tmpfs defaults 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs noauto 0 0
Reminder to myself: Check supplies for more compatible SDRAM sticks.

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