Yes Joey I agree with you, this pin thing is great.

??? Why ???

I think warning should exist not for pinning but for running
testing/unstable package IN GENERAL.

Let me try to defend why pin is great from non-programmer's view point.

I can say it has been working very nicely for me.  No flame but I think
it really depends on what you want to achieve with it.

If dependency try to pull something from unstable, if properly set, it
should stop.

I do not blame you.  Art of setting pin values are not easy to
understood by normal person like me.

If you had hard time with official document, following may help.


This comes with 3 example files for /etc/apt/preferences


(If you find I am wrong in instruction, please elucidate me.  I am
afraid my way may not be optimal.  I never read the source and reached
these set by trial and error.)

I tend to pin some essential files to safer distribution while allowing
to access to other branches.

libc6.      Always choose safest one as default.
            Manually upgrade to known good ones.
gnome-*     Latest.

Something like this.  The choice of pin changes with distribution

I think dselect accessed through apt-method honors pin scores and
provides the best score one as the choice.  You just do not see all the
alternative versions with pin scores.  It may not be best you hope for
but very functional and useful for me.
