I guess those instructions are a bit outdated, readonly volumes do not
have versionvectors and can not be cached by Coda clients. Which is kind
of annoying for your root volume during disconnections.

You can remove all ACL's except for "System:Anyuser rl" which pretty
much makes the root volume read-only. (System administrators can still
add an ACL whenever they need write permission).
