I gave it a try, but AFAICS, when the REPL is started as “internal”,
guix-main.scm isn’t loaded, and thus “Install” fails:

--8<---------------cut here---------------start------------->8---
scheme@(guile-user)> (process-package-actions #:install '((58935712 "out")) 
#:upgrade '() #:remove '() #:use-substitutes? #t #:dry-run? #f)
;;; <stdin>:11:0: warning: possibly unbound variable `process-package-actions'

()>:
<unnamed port>:11:0: In procedure module-lookup: Unbound variable: 
process-package-actions
--8<---------------cut here---------------end--------------->8---

Did I miss something?

Besides, I like M-x guix-generations, pretty cool.  :-)

Yes, that makes sense, one could use it from the *Guix Generation List*
buffer.

Regarding package installation/removal/upgrade, I think it would be
great UI-wise to support transactions that perform multiple operations.

I was initially thinking of something similar to what package.el does:
marks packages from installation/removal, and then hit ‘x’ to execute
the transaction.  So the current “Install” and “Delete” buttons could be
changed to just mark things for installation/removal.

WDYT?

Thanks,
