Greetings, A recent thread here reminded me of this utility, and I've run it on four machines since the latest perl update. In three cases it all went swimmingly, but on the fourth it tried its damnedest to remerge dbus with USE=systemd, and so start converting the whole system to systemd. This system is almost identical to one of the others.
I had to put sys-apps/systemd into package.mask, after which perl-cleaner ran OK, but emerge -c stumbled over nine packages wanting 'dev-lang/perl:0/5.38=', which was the previous version. Next I remerged those nine, after which emerge -c removed 98 packages! Most of those seemed to be useful only on a GUI system, which this one doesn't have (and those 98 shouldn't have been present anyway), so I let it go ahead. The long neglected (here) revdep-rebuild didn't want to rebuild anything. I really dislike mysteries. -- Regards, Peter.
