After unmerging spamassassing (emerge unmerge spamassassin), I was left with spamd in /etc/init.d/. qpkg -f /etc/init.d/spamd does not return any package as owning this file. The header of /etc/init.d/spamd indicates it is from 3.0.0-spamd.init. Should this file be left behind? It definitly uninstalled other pieces as /usr/sbin/spamd is gone.
Unmerging ebuild never deletes anything in CONFIG_PROTECT paths. See `man make.conf` and `emerge --help config`
