What is a clean way to obtain Angstrom Linux to boot up and open the shell without asking to log in?
回答1:
This simple answer took me hours to find. For those of you who don't have /etc/inittab the following worked for me. In
/etc/systemd/system/getty.target.wants/serial-getty@ttyO2.service
change the line
ExecStart=-/sbin/getty 115200 %I
to
ExecStart=-/sbin/getty -a USERNAME 115200 %I
I partially figured this out on my own from reading about getty in /etc/inittab, which led me to ExecStart on my system, and a quick google search led me to https://unix.stackexchange.com/questions/42359/how-can-i-autologin-to-desktop-with-systemd which gave me the auto-login syntax of /sbin/getty.

I found a nice way to achieve it. This works for me with Angstrom (on a Beagleboard xM Rev C4).
Make sure agetty is installed (/sbin/agetty is the standard location). It should be included in every Linux Angstrom image.
Create a script file in any location, for example /home/root/autologin.sh. Edit it and add the following:
#!/bin/sh exec /bin/login -f root
Make it executable with the command
chmod a+x autologin.sh
Edit the file /etc/inittab. Comment out (by adding a “#” at the beginning) the following line
1:2345:respawn:/sbin/getty 38400 tty1
and add the following line:
1:2345:respawn:/sbin/agetty -l /home/root/autologin.sh -n 38400 tty1 linux
Hope this helps out there.

My answer is more linux-generic. Without a start of a getty-process you doesn't have a passwort login. Look at
/etc/inittab
starts here a *getty-process? Remove this line and restart your device.
回答4:
1:2345:respawn:/bin/login -f root tty1 </dev/tty1 >/dev/tty1 2>&1
change tty1 for your system configuration, ex) ttyO0, ttyS1, etc..
