devel/buildbot-slave 0.81

>Description:

When one installs buildbot-slave, it is likely that one would like the
daemon start automatically once the software is configured.

>How-To-Repeat:

ls /usr/ports/devel/buildbot-slave/files.  Note no rc script.

>Fix:

Here is a very simple one that I am using successfully.  It can only
handle one buildslave environment per machine (I am using one virtual
machine per environment).  It will need a few generalizations to make
it ${PREFIX}-safe and Python-version-independent.  Making buildslave's
startup a bit quieter by default would be a nice addition.

#! /bin/sh

# PROVIDE: buildslave
# REQUIRE: LOGIN
# KEYWORD: shutdown

# Add the following lines to /etc/rc.conf to enable buildslave:
#
#buildslave_enable="YES"
#buildslave_directory="/home/buildbot/path/to/slave"

. /etc/rc.subr

name="buildslave"
