Hello everyone,

   I'm  currently  trying  to alter my knoppix(debian) installation on my
   memorystick to save all his changes to a ramdisk and when I want it to to
   sync the changes from the ramdisk to a loopback file.

   Currently the setup is

   the compressed knoppix.sq file mounted at /KNOPPIX

   the loopback file mounted at /KNOPPIX-DATA

   the ramdisk mounted at /KNOPPIX-DATA-RAMDISK

   everything mounted over eachother using aufs /UNIONFS

   everything works so far in the sense that when I edit things in /unionfs the
   changes get carried out in /knoppix-data-ramdisk.

   But now, how do I sync them?

   for that I found the aubrsync script and I execute it using the command

   "aubrsync move_with_wh /UNIONFS /KNOPPIX-DATA-RAMDISK /KNOPPIX-DATA"

   and that gives me the following errors:

   + mount -o remount,ro,udba=reval,noshwh /UNIONFS
   /sbin/mount.aufs:plink.c:223: AUFS_CTL_PLINK_MAINT: Inappropriate ioctl for
   device
   +  mount  -o remount,udba=reval,noshwh,rw,relatime,si=aa3aa37c,noplink
   /UNIONFS
   /sbin/mount.aufs:plink.c:223: AUFS_CTL_PLINK_MAINT: Inappropriate ioctl for
   device

   I'm prety lost now, any help?
