Indeed `dpkg -c ../nsscache_0.49-3_all.deb | grep bin` shows there's a symlink being installed from `/usr/sbin/nsscache` to `/usr/bin/nscache`.
There's no special logic in the upstream to do this. Ah, this comes from the debhelper `dh_link`: ``` dh_link -O--buildsystem=pybuild install -m0755 -d debian/nsscache/usr/sbin rm -f debian/nsscache/usr/sbin/nsscache ln -s ../bin/nsscache debian/nsscache/usr/sbin/nsscache ``` ... which is being performed because of debian/links. So I did this on purpose a while back, I can't remember why, but I guess because upstream was installed to /usr/sbin and I couldn't figure out how to tell pybuild to install to /usr/sbin.
