<PaulePanter>We currently (without guix) manage our own package infrastructure with several versions of scientific packages installed in parallel, and have a wrapper `prun` settings up the environment accordingly. If anyone is interested: https://paste.debian.net/1237947/
<zimoun_>rekado: thanks for your answers about bioconductor and Git. :-)
<zimoun_>PaulePanter: basically, you can have as many profile as you want. So yes, it works with multiple parallel installed versions.
<zimoun_>Currently, mainstream Guix provides only one version of R. For instance, compare “guix shell gcc-toolchain@7 -- gcc --version” and “guix shell gcc-toolchain@10 -- gcc --version” which basically does the dance of ’prun’
