* Fix to remove dots from vserver names (replace them with underscores; dots confuse munin) * Drop support for old (pre 2.6.19) kernels * Replace cat | grep | cut pipelines with a single sed each * Add env.stripdomain (a domain name to strip from the end of vserver names when generating labels; be sure to include the leading dot)
