[bug#72714] [PATCH v4] home: services: Add 'home-sway-service-type'.

[pelzflorian (Florian Pelz)]

Thank you Arnaud for this well-written home-sway-service!

Some comments for you or the one who pushes your patch.  I would
rather not take any responsibility for sway myself.

Typo: Please add 'the': sets up the configuration file and profile packages

Good.  Even though it is a little strange that one would add a home
module (gnu home services sway) to the operating-system configuration,
I know no better place for this `sway-configuration->file' procedure,
since the record is for Guix Home and being able to use it for greetd
is just an extra feature.

Why not (bg #~(file-append #$guix-backgrounds
                     "\
/share/backgrounds/guix/guix-checkered-16-9.svg"))
?  This does not work right now, but could you change bg and
perhaps status-command to accept gexps?

Should be with a colon: resp.@: up

You should run untabify on all of  gnu/home/services/sway.scm
to get rid of nasty tabs.

Otherwise looks really good to me (although I have not cross-checked
the man pages).
