How about modifying start-stop-daemon to have a default of stay, and ask it to made a policy requirement?
That would also allow packages to provide some 'start-stop-daemon property' and conflict with each other when they all provide a modified version...

You're right on that. I wrote a few /etc/init.d scripts yesterday (figures my old luck is back...) and such entries "should" be treated as config files. Once again, that just might be a new entry for the policy (change 'should' to 'must')

As far as packages are concerned. In case of clusters, and in case of /etc/init.d modifications in general, the end-administrator will have the knowledge to play with that anyway. Point being, we might have to impose on the admin to select what daemons he wants migratable, and which does he NOT want.

Related, how do we deal with user-level processes? (Haven't looked deeply in MOSIX just yet) How is migratabilty handled for end-users?
