 echo "Resize zram to match the shipped config"
 # 90-omarchy.conf changed the device size. The migration that first applied the
 # zram tuning is one-shot, so machines that already ran it have the new file on
 # disk and the old device still running; nothing would pick the size up until
 # something else rebooted them.

 # it. Ask it what the shipped config comes to rather than repeating the
 # arithmetic here, where the two would drift apart on the next tuning change.

  # resets it first, and reset returns EBUSY for as long as anything still
  # holds it open. That leaves a "Job failed" from systemd in the migration
  # output and still ends up asking for the reboot, so go straight there.
