Is it just that you can't run mixed Firefly and Infernalis versions at the same time during an upgrade or is also the on disk format changing so that Infernals daemons won't understand the Firefly data structures? This is bad for Debian as the current stable release contains Firefly and the next Debian stable will likely contain the LTS release scheduled after Infernalis. So there won't be a Debian stable with Hammer. But upgrades are important and we would really like to have an upgrade path From=20one Debian release to the next. Is there anything that can be done about this? At least having an offline upgrade option would be nice, if an online upgrade is not possible. How are other distributions planing to handle this? Ubuntu will likely have a similar problem at least for LTS to LTS upgrades.
