    Hello,

    Running the test suite (`make check`) gives me one of the tests failed.

    This is from test-suite.log

    The summary is:

    # PASS:  772
    # SKIP:  4
    # XFAIL: 0
    # FAIL:  1
    # XPASS: 0
    # ERROR: 0

    I'm novice in Guix, can anyone give me a clue?

Actually there are two possibilities. I'm trying to narrow this down now.

There is a bug: https://bugzilla.kernel.org/show_bug.cgi?id=183461

in our bug tracker that might be affecting you, or the shared mounts

I noticed much later. I'm going to investigate this and report back.

 

Can you please write the type of system you are building guix on?
We recently discovered that on systemd based systems pivot-root
might fail because of shared mountpoints.
