Thanks a lot Antoine for the feedback, my fault for not checking a full shutdown
with newhidups as i used to do with the serial-line models! i was hopping that
the new second unit i bought (usb one) work fine as the old serial i previously
had :(

At this point, and having that mgups guys should also include /etc/issue
detection for CentOs during mgeups install (as Arnaud told me in the past) i
raise a question: Are they going to include a new release in the mgeups
repository for RH based systems? I don't know how this kind of 3rd party pkgs
are integrated in the main stream and at the same time im not the one to tell
how to do it but just to clarify this now having you release the new rpm.

I would like to know the feedback from CentOs maintainers as well.

I agree with that and also i think MGE ppl have affordable hardware with good
facilities to check the status of these units (really dont know how many people
are using this units but i think there should be a lot, my company is using
several units also) and integration with RHEL and based systems IMHO could be
better.

Again, thanks a lot for you hints Antoine

Salut vieux poilu! :)
