Including maintainer scripts/triggers, or only unpacking? Does sync work if it doesn't know the cache mode (I get "No Caching mode page found"/"Assuming drive cache: write through" from sd on each boot)?I don't think that sync should be needed, as dpkg already syncs all the files it writes
I was at the login prompt: does sysvinit wait for rc.local to finish before displaying that?If you're sure that dpkg was no longer running at the point you rebooted,
