Yep, I noticed this as well and reopened bug #537241 because of it last
week.  I suppose a new install does not care if it is hit with this bug,
so probably wants to disable the syncing.  So do things like build
daemons since they will just throw out the chroot and extract the
archive again after a crash anyhow.
