Apff, yes, that’s a problem.  Guix clients connect to the build daemon
over a Unix-domain socket, and that has a shameful 108 character limit
on GNU/Linux.  Thus, all the test cases that try to connect to the build
daemon fail.

As a workaround, you could try to build in a shorter directory, if
that’s an option at all.

Alternately, you could try changing the ‘test-env’ script to use
relative directory names instead.

Can you try and report back?

TIA,
Ludo’.
