applied thanks, added a verbose_description (nice for the online docs) a
comment for the rollback case and used 'vmgenid' directly instead of the
$1 when restoring a backup, code is easier to read and safeguarded against
a accidental regex insertion between matching vmgenid and printing it out
to the new conf file.
