I have exim-4.34-r1 and postfix-2.1.1 (both with USE="mailwrapper") installed, and whenever the system is booted or anything re-caches services, I get the following warning: * Caching service dependencies... * Service 'postfix' already provides 'mta'!; * Not adding service 'exim'... I don't know if this causes a problem, but it certainly looks nasty. I'd have thought that, at the very least, if we have multiple candidates for a virtual, then we don't want to complain too loudly. Is there some way to configure which one is the default? Reproducible: Always Steps to Reproduce:
Worse, after removing postfix again (and it *doesn't* appear in /var/cache/edb/virtuals) I'm still getting the same error!
Actually, I missed the fact that removing postfix didn't remove /etc/init.d/postfix - so the problem does go away if only one MTA is installed...
It's a "bug", but only a cosmetic one. There's just no good method that I've come up with for the dep caching to figure out which mta is the "true" mta. We could write a generic mta init script that checks rc.conf (or /etc/conf.d/mta), but the qmail family of mta's is started in a very different way than the other mta's. So, since running multiple mta's is a reasonably advanced thing to do anyway, I'm leaving it up to the advanced user to decide what to do about the init scripts. (The simplest is to do nothing, and ignore the depscan complaints. The next simplest is to remove the "provide mta" line in the non-default mta, or just remove the non-default mta's init script entirely.)
