yes, as you requested it explicitly:
different devices as well as making sure to NOT
execute scripts from a present GRMLCFG device.
If it is ok to run scripts at a present GRMLCFG device all works :)
It would be nice to be able to provide the name of the GRMLCFG device, giving
the user the possibility to use different devices as well as making sure to NOT
execute scripts from a present GRMLCFG device.
