The entire concept sounds very good, since it'll allow things to be
more automatic, but at the same time, this plan doesn't alienate
knowledgable users from their modules.conf.

Couldn't the filename simply be "mod.ppp", and then the contents would be the
literal definitions to be added to modules.conf?  Then we don't need a parser.
Or do you want to be able to add more advanced functionality, such as nested
conditional statements?  If so, we may want to look into using "cpp" instead
of writing our own macro processor.

Explain how you'd like to handle devfs?

We could create a script called "mod-update" (companion to env-update and
rc-update).  Eventually, maybe we'll have an administration frontend called
gentoo-update :)

We should call the option MOD_UPDATE (yes/no), or create an option called
UPDATE which contains a list of "auto"-features to update, for example:
UPDATE="mod env devfs"

Once the new modules system is working, I think it should be enabled by 
default.
