That begs three questions.

1) So, since I couldn't copy the entire tree to disk (see first post), either
I did something wrong and I'm trying to find out why cp isn't copying certain
empty directories *out* of the cramfs, or the docs need to be updated with
appropriate mkdir statements to flesh out the resultant missing empty
directories.

2) Did you mean see mkfs.cramfs.c?  I don't have any man page for it
installed on Fermi SL 4.  Anyone else?  I was hoping not to have to read raw
C source code just to find out how to redo an important part of SIS' bootup
procedure.  If I have to in order to flesh out the docs, I'll do it, but
first I'll check to see if there's better user-friendly info out there
already.

3) Is that truly a bug in mount, where cramfs mount shows as rw?

Dan W.
