What if, in the alternative, we were able to "include" an executable file?
That would keep you from needing to write specific use cases for just
Windows. Of course, it would also put the burden of actually writing the
ini=>conf translator on the user. I imagine something like this:
include_exec "fetch_from_ini.exe"
It would work just like "include", but it would popen the file instead of
fopening it. An enterprising user might even write something like this
(certainly wrong -- not even looking up right regexes :P):
include_exec "cat nxlog.ini | sed -e 's/^\#/;/' -e
's/^\[([a-zA-Z]*)::([^\]]*)\]/<\1 \2>' -e 's/exec[0-9]+/exec/' -e 's/=/ /'"
However, Justin, in the mean time, you might be able to accomplish
something similar with a startup script that translates the ini to conf.
I'm super-rusty on my GPO stuff, but I think you can have all the boxes run
a set of scripts after they update their settings. If you can add a script
that just seds the ini into conf right after a settings update, you might
be able to get the centralized management you desire.
That said, you should check out the log4ensics stuff. It does the dynamic
management and quite a bit more.
