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,
