Hi Guix Team,

Is there any plan to include "proot-static" with Guix Binary= releases ?

My request is motivated by the fact i'm looking for a way to use/insta= ll Guix only with the bin release on a non-privileged environnement (HPC, n= on root user) without the need to use guix pack on another computer to crea= te a "pack" only for this package for every architecture i would like to install Guix on.

This way, if namespaces are not available, we could use Guix with Proo= t without any more efforts.

Best regards,

Indeed. (I assume you read , which is about running software from a pack, rather than running Guix itself.
