I'll move the swap to the partitions then, though it is a moot point as
the machine has 4G physical RAM and runs with a load such that usually
about 2G is cache... I assume that if it never swaps, it never matters.

But what I care about is the raid-5 shrinking issue... does anyone know
if there is a reasonably safe way to shrink a raid-5 device (size, not
number of drives) that is superblock format 0.90?  I assume the --grow
just forces the superblock based on the _device_, but if I shrank the
_device_ before I shrank the raid, it wouldn't find the superblock in
the first place...
