Could it be that a concurrent process removed ‘t-profile-21734’ behind
our back?  As you can see, that symlink was available just above.

Or is it 100% reproducible when running

  make check TESTS=tests/guix-package-net.sh

?

Thanks,
Ludo’.

I have no idea! This time I did ...

make -j check

... but I often do ...

make -j 10 check

... so I repeated ...

make -j 10 check

... a few times thinking maybe another test could delete the link, but
could not reproduce the error. BTW, from each 'make check' I do end up
with a dangling link like ...

t-profile-alt-10987-1-link ->
/home/g1/src/guix/test-tmp/store/hwr4xiqd60wrh033wvjljly50j6d39dg-profile

... is this normal?

It is not reproducible ... except by deleting the profile while the test is
running ;-)

The t-profile-NNN name should be unique for the shell that runs
tests/guix-package-net.sh, so I don’t think running ‘make check’ like
this can trigger the problem.  The only way it could happen is if you
explicitly did “rm t-profile*” or similar while the test was running, I
think.

Nope, tests/guix-package-net.sh was leaving these files.  I’ve just
fixed it.

Well I’m closing this bug, but do reopen it if it shows up again!

Thanks,
