yes, the message is silly, because ".knoppix" is perfectly valid for a vfat filesystem.
these dot names are vastly used by cygwin, the unix emulation for windows.
no promlem here realy.

i have a /mnt/cdrom
multiple mounts should also be possible. e.g. look how /ramdisk is used
in knoppix.

already possible and i like the current name.

only if it asks about remounting. i hate when software does something
dangerous without asking me.
if it presents a message box and presents different options it will be fine.
"keep RO -> copyhome
remount -> persistent home in .knoppix"
but that's before running the GUI so it would be like the dialog for swap
memory on computers with 64MB RAM.
