'make check' cannot be run as super-user or it fails

Binary package hint: upstart

Hi - got this error when running "make check" as root - does not happen when running as non-root :

...with error after modification of job
BAD: wrong value for file, expected (nil) got 0x636a00
        at tests/test_conf.c:708 (test_source_reload_job_dir).
/bin/sh: line 5: 25048 Aborted ${dir}$tst
FAIL: test_conf

Please either skip this test if running as root or drop relevant capabilities or become non-root user for this test .

Thanks !
