[igorpecovnik]

Description

This information is (will be) used in motd to show status and within new armbian-configng to perform upgrades.

oracular=csc;upgrade=none
buster=eos;upgrade=bullseye,bookworm,trixie,testing
bullseye=csc;upgrade=bookworm,trixie,testing
jammy=supported;upgrade=noble,oracular
focal=eos;upgrade=jammy,noble,oracular
noble=supported;upgrade=oracular
sid=csc;upgrade=none
bookworm=supported;upgrade=trixie,testing

with sorting added in next commit:

bookworm=supported;upgrade=trixie,testing
jammy=supported;upgrade=noble,oracular

Could mislead users that upgrades were some sort of supported.

This here is only a configuration file. Perhaps replacing word "upgrade" with something else is enough? We will provide an option in the armbian-config with a proper warning. But armbian-config needs to know what is possible.

ok

Perhaps changing oracular=csc;upgrade=none -> oracular=csc;alt=none ? In case someone looks into this file to not raise questions?
