improper shutdown - root unionfs and power off

[krishna.murphy]

By the way, this is a hard disk install, ie the ( remastered ) readonly compressed rootfs is sitted on the ntfs
harddisk.

I have myself to blame if it is my ( remaster/customization ) fault. But if I remember correctly, since day one of
using vanilla knoppix 6.2, the knoppix-data.img was never unmounted properly which resulted in the need
to fsck when booted ( the fsck is coded in minirt.gz).

I don't have a file knoppix-data.img in my setup; knoppix-data.aes is in my KNOPPIX folder (which comes from the "poor mans install" only, I think), an encrypted "persistent store" that is merged with the KNOPPIX file in that folder to become the effective filesystem. The difference is most likely due to hd-install nature of your setup.

Cheers!
