have a swap partition). This makes the whole setup terribly slow.
I notice that this ramdisk is only used marginally for hosting /home and
/var (through symlinks). What I tried to do to make things faster, is to use
a small ext2 partition on hard disk. I have copied the contents of
/ramdisk/home and /ramdisk/var to the hard disk and changed the symlinks
accordingly. Then I unmounted the ramdisk (using the -f option).
But this action did not released any additional RAM (checked with the
command free). What can I do to make full use of the available RAM?
Thanks for any help

Apparently, normal system operation already uses all the available 'real' RAM memory (approximately 29 MB of the available 30 MB).
What do you mean by your comment regarding the cheats? I don't see any code to bypass the ramdisk.
