commit: http://git.buildroot.net/buildroot/commit/?id=fb7226ca2f185577f656b422f9e6a73304de71e9
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

In sysvinit inittab the "id" field (first field) must be no longer
than 4 bytes, and is not used by init to determine the output
terminal. Therefore, we adjust the strategy used to modify the inittab
file according to the getty configuration.
