Sigh.

I see two simple typos. The '&' is special to sed and is lost in the resulting line. It needs to be escaped with \&. Also not a problem but since '/' is avoided as the sed substitute character it means that they don't need to be escaped in the string and one of them had been missed anyway. As a matter of preference I would continue to use getty for this and have it set up the tty state. Then it can call /bin/login. Therefore I would still continue to use getty. This works in Wheezy 7 but not in the old Squeeze 6. (Note that getty -a username is new in Wheezy 7 and doesn't exist in Squeeze 6.) Then the redirections are no longer needed. It is just a small amount simpler then. I tested this and it worked for me on a Wheezy 7 install. sed -i 's,1:2345:respawn:/sbin/getty .*tty1 *$,1:2345:respawn:/sbin/getty -a USERNAME 38400 tty1,' /tmp/inittab Change /tmp/inittab to /etc/inittab which I left intentionally so that it couldn't do harm by a stray paste. I will mention that in Wheezy 7 the getty annoyingly to those of us who care about boot errors automatically clears the boot screen unless the --noclear option is given. You might want it. YMMV. 1:2345:respawn:/sbin/getty --noclear -a USERNAME 38400 tty1 Bob
