The only thing needed to update them is a successful build (in meta
mode), it is so painless that many developers at Juniper remain
completely ignorant of them ;-)

Only if it builds in meta mode I think.
You can generate meta files during a normal build but they are valuable
for debugging mostly.  Perhaps with a heavy set of filtering they might
be used to glean correct tree dependencies - but building in meta mode
is simpler.

Note, and out of date Makefile.depend does not guarantee a build
faliure, it introduces a race condition though, each race has its own
likelyhood of win/lose of course, so there is often quite a bit of
tollerance for out of date dependencies.

Anyway, it's a bit early to be worrying about that.

Thanks
