Hi,

Simon Tournier <zimon.toutoune <at> gmail.com> skribis:

> $ guix shell -m manifest.scm --export-manifest

‘--export-manifest’ is meant to “translate” a command line, which it can
do faithfully; there’s no way it could possibly “recreate” what
‘manifest.scm’, which may contain arbitrary Scheme code (and someone who
already has a ‘manifest.scm’ file probably doesn’t need
‘--export-manifest’).

It’s necessarily a lossy process.  Some of the transformations
‘manifest.scm’ uses may be recorded as metadata in manifest entries, but
others, such as uses of ‘package-input-rewriting’ here, inevitably get
lost.

I would close it as not-a-bug; WDYT?

Ludo’.
