if I could recover from this sort of failure. I'm running NetWorker
backup software to preform recovery of files.
But when booting into recovery mode, however, there is no "/mnt/
sysimage" folder, as described in Red Hat's documentation. But there
is an "/mnt/runtime" folder that seems to contain the remaining files
on the hard drive.
How come there is no "/mnt/sysimage", and what is "/mnt/runtime"? How
can I access the files in a write-enabled mode so that I can perform
full recovery?
I suggest the /mnt/runtime is only the files on the rescue disk. After erasing
the system one does not expect to find it. That is sort of what rm is good at.
The only other possibility is that the kernel crashed before rm could complete
its work. If it was an ext3 filesystem it would likely crash on a journal commit.
As for myself, I really have no interest in testing my suggestions nor in
trying to duplicate your experiment. I might go so far as to say no one in his
right mind expects to rescue a system deliberately destroyed this way. It is no
the sort of thing one designs for.

Thank you for your input.
But maybe I didn't make myself too clear on what I'm aiming at. :)
I need to figure out how badly a system can be damaged before I have
to perform a fresh OS install (with recovery of necessary files). If I
can recover from a failure by booting into rescue mode and running the
recovery software, I probably should consider that solution before
going for the fresh OS install option.
And I was not sure of how much of the OS installation the rescue CD
would require to be able to mount it in order for me to run recovery
on it.
