After upgrading munin from 2.0.8-r2 to 2.0.9-r1 to fix bug 448414, munin-cron stopped working.
Steps to Reproduce:
1. Install munin-2.0.9-r1
2. Run "sudo -u munin /usr/bin/munin-cron"
Failed to create rundir (/var/run/munin): Permission denied at /usr/libexec/munin/munin-update line 39
I tried to unmerge / emerge again munin, with the same results.
Ah, Portage likely removed /var/run/munin during the update, I see what's going on there. Will fix.
Fixed without revbump (a reboot would solve the problem anyway).
