I'm sorry but Carsten is right. I routinely add the snippet below
precisely because packages installed from experimental are not upgraded
from experimental without it.
Package: *
Pin: release experimental
Pin-Priority: 150
And it's also the reason why APT now supports a "ButAutomaticUpgrades: yes"
field to complement the "NotAutomatic: yes" field. The result is to have a
priority of 100 instead of 1 (backports.debian.org uses it).
