You could also set unstable pin-priority to 100. This setting will
allow upgrades to packages from unstable as new ones become available
but will prevent additional packages from unstable from being
installed automatically when you do an apt-get upgrade. When the
unstable package enters testing, it will be tracked from that point as
a testing package.

Use setting like in my prior message. Since testing will become the
next stable release, you should keep tracking testing for now. When
sarge/testing gets released as stable, you will need to change your
pin-priorities to 990 for stable and less than 100 for
testing and unstable.

Only stable packages will get upgraded when you do apt-get upgrade.

Since pin-priotities of testing and unstable are less than 100, any
packages from testing or unstable will not be upgraded by a simple
apt-get upgrade. You will need to do an apt-get install to get a
upgraded package.
