Thanks again Chris. That makes sense now. I would now expect:

 file:// file:///private/sstate-cache

to work just as well as:

 file://.* file:///private/sstate-cache/PATH

I'll try that later.

Anyway, I ended up with:

 SSTATE_MIRRORS = "\
 file://Debian-[^/]* file:///private/sstate-cache/Debian-6 \n \
 file://Ubuntu-[^/]* file:///private/sstate-cache/Debian-6 \n \
 file://.* file:///private/sstate-cache/PATH \n \

along with a tweaked version of your lsb_distro_adjust hook from
http://git.yoctoproject.org/cgit/cgit.cgi/meta-mentor/tree/conf/distro/include/sstate.inc
to collapse Debian minor versions.

This seems to do exactly what I want.

Thanks to everyone who responded.

Mike.
