However, I find it easier (and probably less risky, as it's possible that the SD card isn't ready when rcS-late is run) to edit /etc/event.d/rcS-late to use /sbin/deb/swapon -a, i.e.

Code:

 /sbin/swapon -a || echo "Failed to enable paging partition."

(NB, /sbin/ might not be there, I'm working from memory as I've already changed it) to:

Code:

 /sbin/deb/swapon -a || echo "Failed to enable paging partition."

..and then edit /usr/lib/genfstab.awk so that the swap partition is mounted with pri=1, i.e.

Code:

start == 1 && $6 == 82 {
 printf "%s none swap sw 0 0 \n", $1
}

becomes

Code:

start == 1 && $6 == 82 {
 printf "%s none swap sw,pri=1 0 0 \n", $1
}

.. then /sbin/deb/swapon -p 1 /dev/mmcblk1p2 (or whichever partition the swap is on) in a custom event.d script which is run at a later time.

I've been experimenting with compcache, using disksize of 128M (rather than memlimit) and then setting the ramzswap priority to 2 (so it is used first), leaving the striped file-based paging file for when it is used up. Unfortunately I think the swap free notify patch that I modified to work with Nokia's swap_remap isn't completely right, as I'm getting lots of "BUG: scheduling while atomic: kswapd0/15/0x00000000" in dmesg - unless that is a direct result of the striping, of course..
