Anyone have any experience managing existing debian / deploying new based devices that are disconnected from the internet? subscription-manager and from atix requires extra dependencies that a minimal install of debian 11 lacks. bootstrap.py seems to only support yum/dnf at the moment.
So I’m curious if anyone else in the community has had to deal with this, and may have some suggestions? Only way I can think of is to build custom images for these devices with the necessary packages / gpg keys in stalled and setup to the point where all I have to run is subscription-manager blah blah activation key.
And yes, I’ve dried searching the googe man page 
Thanks!
