Agreed, but for your friend Justin Case, I figure that having a bit of swap acts as an airbag in the event of a head on collision with some runaway memory hog, in which case the system starts to thrash instead of just run out of memory. I have an Athlon 3800+ AM2, 1 GB ram, and two 80 GB Seagate SATA drives. Each drive has three partitions and each drive is partioned the same. Partition 1, 64 MB, is raid1 together and has /boot on it. Partition 2, 16 GB, is raid1 for LV-system on which all the other system partitions, including swap, are LVs. Partition 3, the remainder, are each directly part of a LV-user and on that I have LV-home (I decided I didn't need raid1 for /home since I have good and frequent backups). All this was set up from Etch's installer. I can't tell you how much performance hit swap takes being on LVM/raid1, but I figure that since swap causes such a hit anyway, it won't make much difference. Etch has been rock solid for me. YMMV.
