Even the Launchpad is close, I would like to share addl. information for this lineitem...

A new group 'zkeyadm' needs to be created and all users intending to use
the tool must be added to this group. The owner of the default key
repository '/etc/zkey/repository' must be set to group 'zkeyadm' with
write permission for this group.

Not sure if another LP is required for it....
