Yes, blank is the same thing as /.

Well, you should not be trying to restore /sys or /proc. If you have backed
them up, then you will need to exclude them from the restore. These are
"virtual" directories created by the OS, and writing into them could cause
lots of damage.

If you rebooted the server without completing the restore, there is little
chance it will boot up.
What does "loading vmlinuz..." mean? If you did not restore everything
in /boot AND if you did not rewrite the boot sector with grub (or possibly
lilo), there is no chance that your system will boot.

They are actually directories that you should exclude from the backup, and
there are several places in the doc that show examples. However, it is true,
you sort of have to "know" as it may not be as explicitly stated as it should
be -- I'll look at the document in the near future.
If you have specified directories or filesystems such as /proc and /sys in
your backup, then you can still do a restore, but you will need to explicitly
exclude them.

Well, hopefully, I will have the new rescue working the way I want in another
day or two, and then documented within the next week. You will be free to
try it in mid-October, and by then it should be working at least for SuSE
10.1 systems, which is what I am running, but I will be on vacation (a real
vacation this time) from mid-October to mid-November.
