Hello,

Martin Castillo <castilma <at> uni-bremen.de> skribis:

> This patch makes AcceptEnv configurable from config.scm.

Nice!

> Questions:
> Is the dash in environment-variables correct?

No, just “environment variables”.

> Why are there always two spaces after a period?

It’s inherited from an (old) convention honored by Emacs notably that
mimics English typographic conventions regarding spacing after
end-of-sentence periods.

> Is @option the correct annotation for AcceptEnv?

@option is normally for command-line option, so I’d just use @code.

Overall the patch LGTM, so the comments below are really nitpicking:

> +@item @code{accept-env} (default: @code{'()})
> +List of strings describing which environment-variables may be exported.
> +
> +Each string gets on its own line.  See the @option{AcceptEnv} option in
> +@code{sshd_config(5)}.

I’d write “… in @code{man sshd_config(5)}.”

> +@example
> +(service openssh-service-type
> +         (openssh-configuration
> +		  (accept-env '("COLORTERM"))))
> +@end example

Please add a sentence describing the example, even if it seems obvious.

> +  ;; list of strings
> +  (accept-env            openssh-configuration-accept-env
> +                         (default '()))

We usually avoid abbreviations, so that would be “accepted-environment”
(see <https://gnu.org/software/guix/manual/html_node/Formatting-Code.html>).

Could you send an updated patch?

Thanks,
Ludo’.
