Subject: procd: Make askconsole work again when no tty is specified in inittab
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fprocd.git;a=commitdiff_plain;h=dc3ea949544090f91a24b05c5fde0bd9ab87f2ce;hp=44803f0b48e6b0bbc56b1f9f8c2ea9c8e1003302

procd: Make askconsole work again when no tty is specified in inittab

Consider:
::askconsole:/bin/ash --login

askconsole( ) checks for the existance of the tty, but if none is
specified it will skip the remainder of the function. This means
fork_worker( ) is never called and no process is spawned. This
would leave routers without an initial console.
