Using zram to compress pages did not provide enough memory to run
Firefox, Node, and Python for an extended period of time. Here's hoping
swap-on-NBD will be fast and reliable enough to work.
Note that systemd's default behavior with respect to swap areas is to
enable them all rather early in the boot process, before the network is
fully configured. As such, we have to use the *noauto* flag to disable
the default dependencies and add our own in a later target.
