Public bug reported:
Fresh install of 16.04 amd64.
Installed the package and noticed whilst update-initramfs is running
that cryptsetup reports two swap devices, one - a UUID - of which
doesn't exist on the system. Eventually tracked it down to a UUID in
/etc/uswsups.conf but have not been able to figure out where it came
from originally.
$ update-initramfs -u
