[Patchew-devel] [PATCH] testing: do not pass /dev/null stdin to script(1)

Posted by Paolo Bonzini 6 years ago

The script tool exits immediately if it encounters an EOF on stdin.
Therefore, we must pass a pipe or the testers' cron jobs will exit
immediately and incorrectly.

The script is still run with /dev/null as stdin, to avoid hangs
on input.
