IIUC the problem you have is that in a Guix build environmnent, Guile
tries but *fails* to autocompile ".scm" files because it doesn't find
any directory that it can write on?
Even if I would not recommend relying on autocompilation in a build
process (or anywhere else) I agree that it would be reasonable to have a
way to autocompile ".scm" files in a Guix build environment.
Since /tmp is writeable in a Guix build environment and in most POSIX
systems (I guess), Would it make sense for Guile itself to fallback to
/tmp for its compilation cache?
Thanks.
