(note that the samba4 source package has been removed in Debian, there
 is only the "samba" source package which now ships the binary packages
 previously provided by the samba source package).

This means libtalloc2 will have to depend on Python; libtalloc2 has quite a few
reverse dependencies that don't require Python at the moment.

Several other things in samba-libs depend on libsamba_python.so.0 IIRC.

I think this is the most reasonable option, though it's a pity we'd have to
package something so small separately.

Hope this helps,
