I've somewhat belatedly gotten around to using this and encountered a
couple of issuettes:

1. There was a spurious-looking RRECOMMENDS_${PN}-dbg in bitbake.conf
which was causing ${PN} to be dragged into the image whenever ${PN}-dbg
was installed.  This is undesirable because it means that, for example,
any image which includes sysvinit-pidof will end up installing sysvinit
and this might cause quite drastic changes to the behaviour of the
resulting image.

2. Having fixed the above I'm now left with a couple of file conflicts
in the -dbg packages.  For example, sysvinit and util-linux both
ship /sbin/sulogin and so sysvinit-dbg and util-linux-dbg both want to
install /sbin/.debug/sulogin.  This is unfortunate if you have an image
which uses, say, sysvinit-pidof and util-linux-blkid.

I'm not quite sure what the right way to fix (2) is.  I suppose in an
ideal world the -dbg packages would be separated in the same way the
parent binary packages are, but that doesn't look entirely
straightforward to arrange.
