R_MODULES="${ROOT}/usr/share/module-rebuild/moduledb" /usr/share is only for static data. /var/lib should be used for changing data. If I wanted, I should be able to mount /usr read-only.

that is of course assuming we follow the FHS. Which (strictly speaking) we dont. Will look at this sometime.
We don't strictly follow FHS, but I think this thing is followed also on Gentoo. There is a question about this in the end of mentoring quiz (12).
I can make patches for this, if you are not interested.
fixed in cvs. please try 0.5 shortly.
I think you should have moved the moduledb from /usr/share to /var/lib in the ebuild. Now everyone has to repopulate their moduledb and the old moduledb is left as a cruft to the system.
I considered doing that actually, but decided to make a clean break away from it. There are two parts to this. the eclass linux-mod and the module-rebuild script. in this case, the eclass handles what should be done re: the moduledb database. if module-rebuild hasnt already repopulated then it moves the old database to the new location. when this goes stable, it would be prefered that we re-populate than to move the original one. in any case, it removes the old cruft.
