[oe] autologin recipe for gumstix Overo

[Elvis Dowson]

Hi,
       For the autologin.bb recipe that is shown below, the pkg_postinst and the pkg_prerm parts do not run correctly. the /etc/inittab file does not get modified. I've had to manually modify the inittab file by hand, and additionally create a text file /usr/autologin.profile with the text root in the autologin.profile file. 

Could someone suggest how this recipe can be modified so that 

a. the following text in the /etc/inittab file to be modified such that

S:2345:respawn:/sbin/getty 115200 ttyS2 

is changed to 

S:2345:respawn:/sbin/getty -n -l /usr/bin/autologin 115200 ttyS2

and 

1:2345:respawn:/sbin/getty 38400 tty1

is changed to 

1:2345:respawn:/sbin/getty -n -l /usr/bin/autologin 38400 tty1


b. Create a new text file called /usr/autologin.profile with the following text

root


Here are some links to the original instructions:
