It turns out that the above was a local change so that statement was
incorrect. Nevertheless the change probably makes sense anyway.

On eglibc?

I'm having trouble coming up with a way to solve that. I think the
libc6-dbg package needs to RPROVIDE, RREPLACE and RCONFLICT with
libc-dbg but if I add the following:

  d.setVar('RPROVIDES_' + bpn + '-dbg', bpn + '-dbg')
  d.setVar('RCONFLICTS_' + bpn + '-dbg', bpn + '-dbg')
  d.setVar('RREPLACES_' + bpn + '-dbg', bpn + '-dbg')

Then the package names undergo translation and I get:

  Provides: libc6-dbg
  Replaces: libc6-dbg
  Conflicts: libc6-dbg

Which is clearly wrong. :(

How would you recommend I provide backward compatibility for this
change (assuming it is still seen as desirable?)

Thanks for your comments.

Mike.
