We need a perl hacker. Code speaking, I'm not a perl hacker, too bad, but I understood that, looking at yaird coding style a new file EvmsTab.pm should be added to sources that does what you are saying.

This is done with the should-be-added-line 88 in Plan.pm: $ok || ($ok = tryEvms ($actions,$device,[$device,@{$working}])); > - Make sure /dev/ is writable, and mkdir /dev/evms.
