Yes, freedesktop people have given up on many useful things, which is a shame in my opinion (consider the fact that dbus can't be restarted on a running system without causing breakage). That doesn't necessarily need to mean that Debian can't do the right thing, though. If indeed restart after upgrade becomes the default, then that could fix some similar issues. Mean time, if "short downtime" really is important to you, there's a workaround: don't upgrade all your packages with dist-upgrade, but upgrade the important packages (Apache and MySQL in your example) plus their dependencies first (so the list of packages being upgraded is much smaller, and the time between "things go down" and "things are up again"), and *then* do a dist-upgrade (upgrading everything else). Needless to say, this would need some testing to ensure your upgrade will go smoothly, but then if reducing downtime is important, that's true anyway. -- The volume of a pizza of thickness a and radius z can be described by the following formula: pi zz a -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
