Bugzilla Bug 97796

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.

/usr/share:
http://www.pathname.com/fhs/pub/fhs-2.3.html#USRSHAREARCHITECTUREINDEPENDENTDATA
/var/lib:
http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLIBVARIABLESTATEINFORMATION

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.
