the file manual-5.html, section 5.4 "File System Consistency".

This morning I went forward to configure and execute my Coda server, and I
discovered that fsck had no complaints about the data residence filesystem
(if dismounted).

Since I noticed in the mail archives that the docs were being revised, I
probably should have asked before snapping, but I was feeling a bit
frustrated.

Perusing log files more carefully, I spotted the module version number:
5.3.15. Venus doesn't manage to trigger loading of the module. For the
moment my startup script just does "modprobe coda" before starting Venus,
but eventually I need to add to /etc/modules.conf:
    alias /dev/coda coda
(in addition to alias char-major-67 coda) which a standardly configured
devfsd will throw at modprobe at the appropriate moment.

At UCLA-Mathnet our incoming (world writeable) FTP area got used as a warez
distribution center, so I'm sensitive to the issue.  We stomped them, you
can be sure, while preserving the writeability of the directory.

I have another question: I'm trying to create the nonreplicated repair
volumes mentioned in Admin Manual sect. 10.6 "Readonly Replication of a
Volume". This is to make the root readonly. But the script createvol was
removed in version 5.0.0. What should I do: use createvol_rep (replicated
repair volumes), or omit the repair volumes, or leave the root read-write?

Beyond that, setting up the server has gone pretty smoothly, as this kind
of thing goes.
