[yocto] How to have Poky automatically login at boot?

[Aaron Schwartz]

Good tip Andre!

Just adding 'auto-serial-console' to IMAGE_INSTALL results in openvt
complaining that VT1 is already in use and then the user is presented with
the regular login.  It looks like I'll be able to make this work once I
figure out how to disable whatever's claiming that vty, though.

Thanks for the help
