Log:
  devel/buildbot-slave: Add startup script with profile support
  
  Kill a 5+ year old Bugzilla issue [1] by adding a startup script
  support multiple "profiles" to buildbot-slave.
  
  This will save me many 10's of minutes restarting ~15 buildbot
  builders over 3 VM's manually every time the power goes out, or the
  Windows host hosting them needs to be restarted :|

+# buildslave_enable (bool):	Set to "YES" to enable buildslave.
+#				Default: "NO"
+#
+# buildslave_flags (flags):	Set extra command flags here. See buildslave(8)

+#				Default: "buildbot"

+# buildslave_basedir (path):    Location for buildslave base directory
+#                               Default: %%PREFIX%%/etc/buildslave

+# buildslave_profiles (str):    Define profiles names. Space-delimited.
+#                               Default: Empty ("")
+#
+# This rc.d script supports multiple "profiles". When profiles are
+# specified, the non-profile specific parameters become defaults.

+# buildslave_foo_basedir="/usr/home/foo/buildbot"
+# buildslave_foo_uid="foo"
