rc.sysinit is cleaning up /var/run every startup, but the file /var/run/dovecot/master.pid is not removed. Dovecot then does not start. Please fix rc.sysinit to not only delete /var/run/dovecot/*/* but /var/run/dovecot/master.pid too. This directory should be cleaned up even dovecot's check for staled PID file is broken.
I find it hard to believe this has been broken this way since 2004, and no one has filed a bug before now. Is that really the case?
I had to manually clean up /var/run/dovecot/* after unexpected server crash. I wonder why /var/run/dovecot/*/* files are deleted by rc.sysinit but /var/run/dovecot/* are not.

This "fix" introduced a regression. Now rc.sysinit shows an error message: rm: Cannot remove '/var/run/dovecot/login': is a directory
Note that /var/run/dovecot/login is owned by the dovecot rpm, so shouldn't be removed.
