Just a suggestion... put the complete 'new' stuff to the already existing proc folder /proc/stb/info.... it already exists... but can now get 'more info'... So just extend the existing - not create/hack a new one, where we somehow 'never' can agree a good name for (as there is already a folder for it why create a different?)

For multi-boot it would be fine to have a file in /etc that gives and image description (short) in the first row and an extended in the following rows.
