I uncovered a problem while trying to run the tests fddrn/fdsrc.
I tried to run fddrn as follows:
$ bin/fddrn bin/tfdd /tmp/tfd
tfd_init failed: No such file or directory
While debugging this, I figured out that the tfdd path needs to be absolute.
Q: Do you need to do chdir("/") in tfd_tfdd_child()? Can we do that in
tfdd binary?
Since exeve failed, tfd_spawn_tfdd() returned EBUSY. So I guess the check
for ret needs be fixed.

goto fail;
}
ret = connect(state->sock,
