Hello
The installed-os test is failing because the image closure is (again)
bigger than the allocated 1.4GiB in the test partition.
--8<---------------cut here---------------start------------->8---
guix size $(./pre-inst-env guix system build gnu/system/examples/bare-bones.tmpl)
--8<---------------cut here---------------end--------------->8---
reports 1397.3 MiB.
By reverting this commit 0eed77127592323d89f56c215a15374a1aaae110
(introducing an extra glibc to %default-locale-libcs), it drops down to:
1305.5 MiB.
Now multiple options:
* Revert this commit.
* Find other system closure improvements.
* Up the limit to 1.5GiB.
WDYT?
Thanks,
Mathieu

Digging a bit more, I discovered multiple culprits in the image closure
size.
* "openssh" is dragging "xauth" which drags some X libraries (but this
does not account for much).
* "sudo" is dragging "python" for about 100MiB.
* "info-reader" is dragging "perl" (and is in fact the same size as
"texinfo" because of a mistake that I introduced with
614a1e3fa2d731d4719f03912b1b87fb4fd309cb) for about 100MiB.
* The switch to non-canonical version of "glibc" and "coreutils" to fix
system cross-compilation in dfc8ccbf5da96a67eb1cade499f0def21e7fdb02 is
also responsible for about 100MiB.
All in all, fixing all of this makes the closure size to drop below 1GiB
which is already a good first step.
I'll try to provide patches soon.
Thanks,
Mathieu

I also discovered that enabling CONFIG_MODULE_COMPRESS, the size of
linux-libre is reduced by 63%.
This makes the image way lighter.

Now, the big source of improvement could be Guix itself (278MiB without
dependencies).
I think we can go further!
Thanks,

Let’s just set the ‘locale-libcs’ field in (gnu tests) so that it
contains a single libc. WDYT?

Yes, but that’s necessary for “ssh -X”, so I think we consciously made
that choice long ago.

Comes from the Python plugin added in
452244e670467afe0e8ccdfb9ca2980d5a3b4694. No idea what it buys us.

Ah would be nice to fix and add a #:disallowed-references flag there!

Yeah, that’s the price to pay. :-/

Woohoo!

Yep, see my recent message on this topic. :-)
Thanks,

I'll see first if I can get the closure smaller by other means. I think
it would be preferable to keep the tested operating-system as close as
possible to the default one.

Ok, I proposed a work around by introducing openssh-sans-x.

Some python bindings to sudo API, but I moved them to a separate
"python" output.

In fact there were a #:disallowed-references already, but its argument
was also wrong so it went unnoticed. I fixed all of that on core-updates
branch.

I'd like to re-introduce "canonical-packages", without breaking the
system cross-compilation, by using "let-system". See:
https://lists.gnu.org/archive/html/guix-devel/2020-06/msg00093.html.

Yes, thanks for your first analysis :)

Closing this one as the installed-os test has been fixed.
