Error message:
ice-9/psyntax.scm:2824:12: In procedure syntax-violation:
Syntax error:
/home/nl/.guix-home/on-first-login:3:1233: source expression failed to match any pattern in form (when (claim-first-run flag-file-path))
As you can see, there is no body in the "when" expression.
Code in gnu/home/services.scm:438 :
(if (file-exists? xdg-runtime-dir)
(when (claim-first-run flag-file-path)
#$@gexps)
In my case, it appears that gexps is empty, resulting in the invalid syntax.

Ah, yep, that's an issue. That issue was introduced in 6b0a32196982a0a2f4dbb59d35e55833a5545ac6.
I guess this raises a question about how to resolve this: if we have no gexps, do we still want to claim the first run?
If yes: we can add #t (or whatever) to the end of the "when" form to make sure it's never empty.
If no: we can generate an empty on-first-login script that does nothing.
The previous behaviour was to still claim the first run, so I'll send through a patch that does that.

I’ve just pushed something similar to what you provided, Carlo, in
commit e098ba2f499bbddfea50c85058e4077e39b85513.
We should be good now.
Thank you!
Ludo’.

I'm afraid this did not fix the issue. It results in
(when (claim-first-run flag-file-path) (begin))
which leads to the new error message "Syntax error:
/home/nl/.guix-home/on-first-login:3:1272: sequence of zero expressions in form (begin)"

Adding *unspecified* works for me. I.e.:
(when (claim-first-run flag-file-path)
;; GEXPS can be empty, hence 'begin *unspecified*'. Having just
;; 'begin' without '*unspecified*' leads to
;; "Syntax error: ... sequence of zero expressions in form (begin)"
(begin *unspecified* #$@gexps))
The patch is in the attachment.
Cheers Bost

Oops, my bad. (I did check at the REPL that (begin) was fine but forgot
that I was checking the top-level ‘begin’ form, which is not the same as
the sequencing ‘begin’ form…)
