Awesome! It seems to work now -- codasrv starts up without any faults that I

(This is reverting back to the default header file, and just stripping out
that little bit
of code that's got the MMAP dependency on rwcdb_file.c)

I'll try running a NetBSD/sparc[64] or NetBSD/macppc client against my
when I get home in a couple of hours and see how that goes. Hopefully it
will be
fairly well-behaved -- you guys will probably hear from me again sometime
soon if
not :)

This was a first install -- /vice was created from scratch, so there was no
prot_users.cdb file. After running vice-setup & starting codasrv, it seems
to be
about 4K, though that may very well be the minimum allocation unit size on

Thanks everyone on this list for your help & support getting coda running
thus far.
