Re: Trying to replicate guix packages list on another machine

[Julien Lepiller]

It's possible your packages on machine A are from various guix revisions, if 
you didn't run "guix update" or didn't use a manifest to install them.

Eg you run "guix install glibc" at revision A, pull revision B where glibc was 
updated to 2.34. When you list your packages, it still mentions glibc@2.33 
because you didn't update it. Then you try to replicate it on another machine 
by pulling revision B, but that old glibc is no longer available.

Manifests ensure that all packages are from the same revision, although if you 
pull a new guix without reinstalling the manifest, you'll have the same issue 
because you're confusing the guix version from which the package was installed, 
and the current guix version.
