:da#s1b 1 GB swap

:volume-del da1s1d"? How long will this take? Do I run cryptsetup on da2s1e
:before adding the volume?
No, unfortunately there is still one sticking point preventing that
from working. The volume delete code can't remove the root volume
(in a multi-volume hammer mount one is designated as the root volume.
In a single-volume hammer mount that volume IS the root volume for
