[Grml] manual grml to hd - read only root fs

Hi,

I did a simple

rsync -aHSx --devices --specials / $new_os_mnt/

instead of grml2hd. All seems fine just that the root fs is still mounted read only.

what's the trick to turn rsync'ed grml hd image into a normal system, which mounts root fs rw, and mounts other fstab entries as well?

Thanks
