Not sure if better (because it has the same effect), but here’s a
different way to get a “manifest” from the list of installed packages.
--8<---------------cut here---------------start------------->8---
(use-modules (guix profiles)
(ice-9 match)
(ice-9 pretty-print))
(match (command-line)
((_ where)
(pretty-print
`(specifications->manifest
',(map manifest-entry-name (manifest-entries (profile-manifest where))))))
(_ (error "Please provide the path to a Guix profile.")))
--8<---------------cut here---------------end--------------->8---
You can put this in a file “manifest-to-manifest.scm” and run it like
this from a Guix source checkout:
./pre-inst-env guile -s manifest-to-manifest.scm /path/to/.guix-profile >
my-manifest.scm
