[CoLoCo] I'm confused about how the disk works

[Kenneth D. Weinert]

OK, so that worked.

How the UUID in /etc/fstab got out of sync with what the vol_id is, I
have no idea.

Setting the UUID in fstab to what the vol_id command shows and rebooting
gives me an autostart of swap.

Hope this helps someone else.
