+Subject: [PATCH] Adjust ejabberdctl for Gentoo jabberbase setup
+
+Set SHELL since the generic jabber user used on Gentoo for jabber
+servers doesn't have a valid shell set by default and fix EXEC_CMD
+otherwise it fails with This account is currently not available again
+due to jabber not having a valid shell.
+
+Also, workaround the assumption that jabber's /root is a directory when
+instead it defaults to /dev/null on Gentoo.
