Hm yeah, toram=grml-medium.squashfs really just copies the squashfs
file to RAM. It *would* be possible to also copy /debs, /scripts,
/bootparams,... to RAM by default - on the other hand I might get a
bugreport that specifying toram=grml-medium.squashfs copies a >100MB
/debs/ to RAM even though the user just wanted to copy the squashfs
file. ;)

So what I'm thinking about is checking for bootoptions like
'scripts', 'debs',... and just copy the corresponding directory to
RAM when booting via toram=.... then. I guess this might be the best
option to match all possible wishes.
