It=E2=80=99s not a true. -p option is good enough in run to run =
automatic fixes, for minor bugs, without relation to boot scripts.
-y option too soft, -n option - too strict, -p is good enough in common =
case for initial fix.
But anyway, is it run from boot scripts command output is logged and can =
be analyzed by automatic tools,
if it run by hand it will analyzed by user.=20
It=E2=80=99s very strange to have some output is in console, some output =
is omitted.
A specially in case user request a -v option.
