same with debian. things go in at the testing end, gets bumped to unstable, and finally reach stable.
but with the ssu you cant. its either all or nothing. you cant tell the app manager that you dont want the kernel updated as you have rolled your own. no you have to take the kernel or the ssu package wont go in, and therefor none of the other packages will go in either.
and its not really clear what the ssu will touch on, until its rolled out.
and as the diablo dialog is not open source, people are left with no chance of a fix, especially as they dont know if fremantle will be new hardware only, or not. the only real saviour here is mer, but it seems hellbent on doing the maxium change rather the minimum change (ripping out and replacing nokia's closed bits).
to me, nokia needs to decide if they want to get into the open source boat, or stay on the closed source pier. right now they seem to hope they can evolve some very long legs by keeping one in each, with the boat sailing...
