I'm uneasy about a 'magic' value, which could be problematic (sorry, did
you have a filesystem named auto?).. is it a problem to have
not set -> auto behaviour
set -> unmount the file systems listed, if any
?
You can do this with eg
case "${swapoff_umount+set}" in
set)
fs_to_umount="${swapoff_umount}"
;;
*)
fs_to_umount="$(dev_free_tmpfs)"
;;
esac
