FWIW: I have 2 patches for tinylogin and util-linux-agetty to provide
/sbin/getty u-a

openembedded-core-contrib/shr
util-linux: use u-a to provide /sbin/getty from util-linux-agetty
tinylogin: use u-a for getty so we can provide /sbin/getty from util-linux-agetty too

I didn't send pull request with them, because I'm still waiting for
previous pull request (with libsdl changes) to be applied.

We can add u-a to mingetty and solve whole problem even for sysvinit
etc...

Cheers,
