I was thinking about this a bit more and there is another option
available to you which would be to pass all the debug sources into the
sysroot as hardlinks to the files in workdir, in much the same way as
we do the other sysroot files (which you don't strip).

Since those files are collected by do_package you'd probably have to
force do_populate_sysroot after do_package but such an additional class
to make these tweaks probably wouldn't be that large and would just
affect performance a bit (with the benefit of the debugging you want).

Just thinking out loud really. My big worry is all the different
codepaths we have people using, equally, you can't get performance
(disk footprint and speed) and functionality in some cases and people
do want to choose different compromises.

Cheers,

Richard
