The idea is simple: if you specify you want to match on realpath (for

matching the basename of the given path and does an extra check to
only return matches where the realpath of the given path will match
the realpath of the partial match it found.
We mostly need to define an API here. The interesting callers do stuff like
$ dpkg -S /lib/x86_64-linux-gnu/libselinux.so.1
/lib/x86_64-linux-gnu/libc.so.6 /lib/x86_64-linux-gnu/libpcre2-8.so.0
libselinux1:amd64: /lib/x86_64-linux-gnu/libselinux.so.1
libc6:amd64: /lib/x86_64-linux-gnu/libc.so.6
dpkg-query: no path found matching pattern
/lib/x86_64-linux-gnu/libpcre2-8.so.0
so multiple file names in a single call, and probably expect the same
file name to be returned to match the response back to the query.
We'd need a new format, for example like
libc6:amd64: /usr/lib/x86_64-linux-gnu/libc.so.6
(/lib/x86_64-linux-gnu/libc.so.6)
and a flag to enable that format, for clients to use. I haven't invested
much time into that yet, my expectation is that the aliasing
infrastructure I've put into the backend handles this nicely, but the
frontend is something that needs to be coordinated.
