Looking at "2.3 Running the Test Suite" of the manual it does not
mention that tests should be run as a non root user.

The test `tests/pack` fails when `make check` is run as a root user.  It
does not fail when run as a non root user.  I found this example by
running `make check TESTS="tests/pack.scm"`.  Is this an issue for many
tests?

I can prepare a patch for the relevant part (parts if this also applies
to `make check-system` as well) in "2.3 Running the Test Suite" of the
manual.

Should `make check-system` also be run as a non root user to avoid
failing tests?

Is there a section in the manual that explains why tests should not be
run as a root user which I can just refer to in the patch?  If not could
anyone provide an explanation which I could include in the patch?

I guess this is one of those (Unix-)cultural knowledge things: it=20
wouldn't even occur to me to build or test anything as root unless=20
explicitly asked to do so :-)

Thanks for the offer!  I think adding yet another gotcha to the=20
manual should be a last resort, though.  Many people still miss=20
them and get into trouble (and on to IRC).

Could we, in order of preference:

=2D make these tests pass even when run as root?  (I guess not?)
=2D skip them and add =E2=80=98n tests not run as root=E2=80=99 to the fina=
l tally?
=2D refuse to even start the test suite as root?

What =E2=80=98root=E2=80=99 means here will depend on why these tests are f=
ailing.

Kind regards,

T G-R

Preventing the issue instead of warning of it in the manual sounds like
a better solution to me.
