Greetings! Maybe I write in the wrong thread, sorry if so.

I see some useful options in /etc/default/mount-opts, which can be overrided in /etc/default/mount-opts-overwrite. I suggest adding swap_opts along with other "*_opts" to pass that to swap section of fstab. I want to pass pri=n to both of my swaps (eMMC and extSD) to have equal priority.
