These tests are skipped when user namespaces are not supported, as per
this condition:
(define perform-container-tests?
(and (user-namespace-supported?)
(unprivileged-user-namespace-supported?)))
… which is true iff (1) /proc/self/ns/user exists, and (2)
/proc/sys/kernel/unprivileged_userns_clone does not exist, or it exists
and contains “1”.
Do these files exist on this system?
Maybe we should just ignore EPERM from (clone CLONE_NEWUSER) but it’s
annoying to annotate every single test that uses it.
>From a user viewpoint, this test failure simply mean that you cannot use
the ‘--container’ option ‘guix environment’ on your system.
Thanks,
