Digging deeper into the livecd: casper removes/purges the
systemd-gpt-auto-generator which normally would
create a swap unit for gpt partitions marked as swap; however, there is
also another nice casper script
13swap which checks partitions for SWAPMAGIC value, and if so, calls
'swapon' $device.

I think casper scripts are part of the livecd-rootfs package, so we can
target that package as well to see
if there is a way disable the swapon bits.

I'm still working on curtin to have it remove target devices from swap if
they're added, however I do think it
would be best to not swap on target devices in the installer env.
