USB booting :: Setup DOS Swapfile

I am running DSL for a USB stick and I want to use the FAT32 Hard drive to place a DOS swapfile. I used the Setup DOS swapfile utility and it created a KNOPPIX.SWP on /dev/hda1.

but nothing happens, the Swap Used stills shows 0/0%

How do I turn on the DOS swapfile?

I should learn to use search better

I found it in "Other Topics"

as root

mount /dev/hda1
swapon /mnt/hda1/knoppix.swp

In the latest RC of dsl v3.1 we now offer a boot option dosswapfile
See change log
