These relate mainly to ppdd root filesystem encrytion.

1. You must have chroot and awk available in /bin on the encrypted root.
2. You must have losetup available too either in /bin or /sbin.
3. You will need a ppddtab in /etc with entries for all the discs you want
   to be "opened" by ppdd automatically. Please do:
   chmod 0 /etc/ppddtab; chown 0.0 /etc/ppddtab
4. Note that the /etc/fstab entries refer to the loop devices.
5. You can usually get away with the normal halt script but you will probably
   get various warning messages (that's the case on SuSE). You need to modify
   the script (/etc/rc.d/halt or /etc/rc.d/init.d/halt) to stop it attempting
   to umount "/" if it is on a loop device. Towards the end of the script when
   the time has come to remount "/" read-only and call the real "halt", you
   need to exec "/initrd/ppdddown".
6. The lilo.conf is typical of what you need.
