How to find the pathname of the swap partition on SD card?
I installed the Disk Info app and in the options, I enabled Expert mode and Unmounted partitions.  It doesn't say "swap", but it shows clearly that it's the only other partition on the SD card and it's the right size, so /dev/block/mmcblk1p2 must be the one:



Swapper 2 is configured to use /dev/block/mmcblk0p3 by default, so I'm glad I didn't go with the default.
