Sounds like quite an interesting project .. Anyway, the most commonly
written-to files by webmin are :
- Temp files in /tmp/.webmin
- Lock files just about anywhere, like /etc/passwd.lock
- Logs and the PID file in /var/webmin
- Some files in /etc/webmin, such as the per-module config files.
However, these are nowhere near as frequently modified as the first
three ..
- The webmin root directory /usr/libexec/webmin. This is never changed
unless a clone of a module is created..
So it looks like you have the important ones covered.
