In 1.0, we finally added nice comments explaining what everything in
/etc/cobbler/settings did. For 1.1(devel)/1.2, I've finally done the
same for /etc/cobbler/modules.conf.
Even if you aren't tracking the devel branch, this should still be
interesting as the config file settings are exactly the same between the
two versions. It lists all the module choices for each config
setting, which ones do what, and some pointers to further documentation
up on the Wiki.
You can take an advance look at this info here:
