Hi Guix!

I figured out this morning that my guix pull profile ("current") was more than 1GB. Looking at the closure, I found a few oddities.

There's gcc in there, which is the second most important contributor after guix-*-modules (150 MB). It's referenced by gcc-toolchain, itself only referenced by the guile-wrapper we build in (guix self). Can we get rid of it?

There are three versions of guile (50 MB each). Can we settle for only one?

Then maybe less important because they're small:

There are two libffi, gzip, zlib, libgc, bash-minimal, xz, pkg-config and libunistring.

We have bash-minimal and bash-static. The latter is a bit bigger than the former. Maybe we can keep only bash-minimal?

50% goes into Guix modules.  There’s prolly room for improvement because
the ‘guix-COMMIT-modules’, which is #1, is actually the union of all the
other guix-*-modules.

I think you fixed that one in 319b8331b2357e12ec9edb9665513c32bef56622.

I think that’s (@ (gnu packages commencement) guile-final), guile-3.0,
and guile-3.0-latest.  However I see only two of them here.

Fixed this one in commit d418031a8cbdea4e2bc5c52ea1b29ad369579bae.

But then, ‘guile-3.0’ being the default, it’s used in a number of
places, like:

--8<---------------cut here---------------end--------------->8---

I can’t think of a good solution to this.

That’s probably due to the fact that there are multiple Guile variants;
annoying.

It’s worth keeping in mind that thanks to deduplication, this costs much
less than it seems in terms of disk space, but it does cost in terms of
bandwidth usage.

Thanks,
