PostmarketOS - Why swap file not on at boot?

[stozi]

I followed the standard arch wiki way to set up a swapfile, and based on 'Install to disk' in the Alpine wiki, which shows setting up a swap partition the normal way, it should work. It does work if I manually turn the swap file on, but it isn't automatically on at boot. I don't know how PmOS works in that there were no other entries in my fstab, but I guess that has something to do with it. any ideas?

cat /etc/local.d/zram0.start
#!/bin/sh
modprobe zram
echo 2G > /sys/block/zram0/disksize
mkswap /dev/zram0
swapon /dev/zram0 -p 100


my solution

i realize that isnt what you want but you can just as easilly sneak in a /etc/local.d/swap.start script that swapons's your swap or call mount -a which should source fstab and try to mount everything therein why pmos doesnt do that and other distros do i couldnt tell ya

If I understand it right then installing zram-init and zram-init-openrc packages might be an option for most users. What do you guys think?

I think that's reasonable, and potentially useful for other devices that pmOS supports.
