Hi John,
I’m seeing this only now, apologies! (I thought the discussion was
continuing in the guix-devel thread, my bad. :-/)

Overall looks great to me and pretty much ready to go. Minor
suggestions.

Should we spell “FHS” out?

This is very much at the core of how Guix works and some of the convenient features, like per-user installation of programs (different versions, for instance) and a declarative system configuration where the system is determined from a configuration file.
Haunt uses Guile-Commonmark, and I don’t think we can use inline HTML
nor footnotes actually. A bit of a bummer, but maybe you can
approximate that with:
`/bin` containing binaries¹, …
and at the bottom:
¹ Blah.
It might be worth mentioning somewhere that the feature is included in
the just-released 1.4.0 now.

The syntax is:
Note that the alt text is not shown unless one disables pictures or
hovers over the picture. So “Or, if you like […]” should probably be
written above the image.
You can test the web site with:
guix shell
and then:
export GUIX_WEB_SITE_LOCAL=y
haunt build
haunt serve
Should we publish it after Jan. 1st, since people are more likely to
miss it during the holiday season?
Thanks!

FWIW I think now would be a good time to publish. Lemme know if/when
you have time for those final touches!

Yes, I think now will be a good time. Sorry I didn't get to this earlier (some unfortunate urgent situations), but I did make most of the changes already. I think just the footnotes, or rewriting them into the text, is all that's left.
Is there anything else I should add, like other images or screen recordings? I think I'll quickly test and add the Tor browser example mentioned on the mailing list at least.

The Tor Browser example would be nice. No other suggestions from me!

Added, with a slight tweak from the original mailing list message (and with credit given). The gcc:lib input is smaller than libgccjit and I believe the DISPLAY/XAUTHORITY sharing is more general (or at least works for me, the original related to GDM which I don't use).
From your previous comments:

I did now, which is more descriptive and I don't think too long. I didn't include the (FHS) abbreviation though (we could).

Ah. I did just that, no links to jump back and forth then. The second note I could just have as a parenthetical paragraph, but the first would be a bit cluttered. So I kept them both as notes, but I'm not attached to the style if we want to change it.

Good idea, noted and linked to the release announcement post.

Fixed (guess the org exporter defaulted to a different style). I didn't see any change in appearance with marking all of these as 'sh' examples, but added that in case it is useful at some point.

Correct, that was supposed to be a caption or before the image. Fixed and added credit for the image.

Thanks, that was handy.
Other than these fixes, adding the Tor Browser example, and some stylistic changes (added some links too), the content should be basically the same as the first version.
Happy to add/subtract anything and anything else if anyone has suggestions.

Slight tweak to the Tor Browser example and just using 'expose' rather than 'share' for XAUTHORITY, as discussed on guix-devel. I tested VSCodium and Tor with that last change and they opened just fine.
Also added a brief comment about the more minimal inputs for the Tor example and how one usually finds it (a lot of trial and error usually).

Hello and sorry for getting into this comment thread.
I have posted a few days ago a question about preserving env vars
when creating a container with FHS emulation:
I think it's something about me not understanding how it works. By
reading my question, is there anything useful to add to the blog post to
clarify its usage?
If not, simply discard this comment :-)
thanks

The ‘PATH’ environment variable, and only this one, is overridden
unconditionally when using ‘--emulate-fhs’; quoth ‘environment.scm’:
(when emulate-fhs?
;; When running in a container with EMULATE-FHS?, override $PATH
;; (optional, but to better match FHS expectations), and generate
;; /etc/ld.so.cache.
(setenv "PATH" "/bin:/usr/bin:/sbin:/usr/sbin")
(invoke "ldconfig" "-X"))
Other variables are preserved, as in this example:

$ FOO=bar guix shell -CF -E ^FOO coreutils -- env | grep FOO
FOO=bar
HTH!

Now filed by jman as https://issues.guix.gnu.org/60566 after discussion on #guix. I think it is a bug (say you want to preserve PATH as you have some scripts in ~/.local/bin for example) and I have a patch to fix. I'll send it to that bug and CC you (Ludo’) as well.
