Er, definitely not. The convention with dpkg-based distributions is to
include the sover as part of the package name; there is no 'libtalloc'
package in Debian, only 'libtalloc1'.
But this does *not* solve the problem that libtalloc1 and libtalloc2 may be
installed, and the dependency tree for a given binary may include both of
them. We can make libtalloc2 Conflict: with libtalloc1 to force an atomic
upgrade of all related packages, but symbol versioning is the more elegant
