You can always get the right source code by running =E2=80=9Cguix build -S
package=E2=80=9D.

OTOH having the source directly in the =E2=80=9Cdebug=E2=80=9D (or =E2=80=
=9Csource=E2=80=9D?) output as
you suggest would be more convenient.

The only downside is the extra size of the =E2=80=9Cdebug=E2=80=9D output. =
 Most of the
time that=E2=80=99s a price people are happy to pay when they are installin=
g the
=E2=80=9Cdebug=E2=80=9D output.  But sometimes maybe not.

For example, I always have gcc-toolchain:debug, libgc:debug, and a few
others in my profile, =E2=80=9Cjust in case.=E2=80=9D  My goal is to have l=
ibc and libgc
symbols when I something goes wrong, but I typically already have
checkouts of these libraries elsewhere.  If the source was in the
=E2=80=9Cdebug=E2=80=9D output, I=E2=80=99d pay a pretty high cost (esp. fo=
r libc) that I could
have avoided.  Maybe this is a corner case, though.

What do people think?
