Re: [Devil-Linux-discuss] Devil-Linux headless/remote upgrade

[Serge L. <ser...@gm...>]

It's just a rough idea, please be lenient :)

usually we have a new image reachable and can mount it from running system,
execute upgrade script against existent config files and save the result (and
backup!). Hopefully we can do it even more than one time :) in order to allow
post factum review and rollback. So the process of config files modification
will be moved from "new" system to "old" system.

However, we rely on aufs format persistence or backward compatibility...
