You may be interested to know that SUSE/openSUSE and Fedora (et al) use
a script wrapper in /usr/bin/pinentry that auto-detects the running
graphical environment, desktop sesssion and installed pinentry binaries
and calls the best available one. I found this to be superior to
update-alternatives.

http://pkgs.fedoraproject.org/cgit/pinentry.git/tree/pinentry-wrapper

The openSUSE one has testamentary support for the newly added
pinentry-gnome3, maybe you can suggest an environment variable for
detecting a GNOME3 session reliably?
