Re: [webmin-l] Question about the MON monitoring component

[Jamie C. <jca...@we...>]

That would be quite tricky, as for Webmin to be able to edit 
the config file it would need to 'undo' the M4 substitions, which
is near impossible.

Solaris uses M4 in its syslog.conf file, but to handle this Webmin
runs the file through M4 the first time you open the module, to
expand all M4 directives. I could do this for Mon as well, but it
would really defeat the purpose of using M4 in the first place, and
would probably annoy users who want to save their M4 directives!

So basically, Mon+M4 is incompatible with Webmin :-(
