Comment 2 for bug 1909353

Another problem here that comes up with the proposed solution above is that if we make snapd modify the config.txt for a run mode system on ubuntu-seed, then booting into a recovery system on ubuntu-seed will use those settings as well, so if a user modifies something in config.txt that is i.e. kernel dependent or otherwise breaks something, they can't go back to recover mode and boot since those settings will still be active.
