Enabling swap
 
I've cloned my OS to /dev/mmcblk0p1 but am having some trouble initializing swap.

1. dd if=/dev/zero of=swapfile bs=1024 count=128000
2. mkswap -c -v1 swapfile 128000
3. swapon -a /swapfile

But top shows zero swap being used. BTW, I'm using 'real' top, not busybox top.

EDIT: Thinking this might be a busybox problem I recreated the swapfile on my pc and moved it to the nokia. Still no dice.

I solved this problem. It seems related to the busybox swapon.
I compiled it for the tablet and it activates my swapfile w/o problem. Busybox (which I'm growing to hate) fails everytime.

Which makes me wonder: if you're running from SD, why not replace busybox totally?

what is the easiest way to do that Jeff? a deb to replace the shell and all the tools would be handy.
