Just tried it, and it works great!

That’s because it’s rebuilding most of the modules, AFAICS.  Perhaps
‘geiser-guile-load-path’ needs to be augmented to avoid that?

There’s ‘manifest-installed?’ in (guix profiles):

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> ,use(guix profiles)
scheme@(guile-user)> (define m (call-with-input-file "/home/ludo/.guix-profile/manifest" read-manifest))
scheme@(guile-user)> (manifest-installed? m (manifest-pattern (name "emacs")))
$3 = #t
--8<---------------cut here---------------end--------------->8---

See tests/profiles.scm for more examples.

It’s definitely appropriate.  :-)

Thanks!
