I mean this:
Code:
dd if=/dev/zero of=/mnt/base-us/swapfile bs=1M count=64
chmod +x /mnt/base-us/busybox
/mnt/us/busybox mkswap /mnt/base-us/swapfile
/mnt/us/busybox swapon /mnt/base-us/swapfile
It's the only combination of /mnt/us × /mnt/base-us which worked for me. It does not work for me with /mnt/us/ (not sure which step exactly).
