Subject: [PATCH] Get rid of useless/confusing subshell

Other function, same stuff like r1.1210 except here there `>/dev/null 2>&1'
hammer is required to silence the ls(1) test.

The make_dev() call is no longer silenced now but does not print on stdout
anyway;  if making the device fails we'd like to know.

Otherwise if probing the disk fails it continues to be silenced.
