Modified:
trunk/varnish-cache/debian/varnish.default
trunk/varnish-cache/debian/varnish.init
Log:
Init-script:
* Move user-adjustable parts from init script to defaults file, expect
$DAEMON_OPTS instead of a whole forest of variables.
* We have a pid file argument, wheee. :D
Defaults file:
* Created alternative default templates, selected a one-backend default
without VCL file.
