My turn to ask a stupid question, because I'm sure your explanation makes
perfect sense to someone who understands this stuff, but I don't: my previous
experience with installing Linux on RAID was with Ubuntu, for which I didn't
need to mess with any of this.
Are you saying that between these instructions:
Add the dm_mod module to the MODULES list in /etc/mkinitcpio.conf.
Add the mdadm_udev and lvm2 hooks to the HOOKS list in
/etc/mkinitcpio.conf after udev.
and the next step:
Once it is complete you can safely reboot your machine:
there should be some additional step(s)?

That seems to say that I should run mkinitcpio, but that step isn't mentioned,
even adumbratively, anywhere on
Hopelessly, completely, lost and beginning to despair....
