I've searched and searched through /etc and init.d but I just can't figure out how to automatically log in some user when system starts.

Is there anyone that could tell me about it.

An where can I find the documentation about the init process of dsl?

dsl's root using /.bash_profile. it su's to user 'dsl' in there, then user dsl's ~dsl/.bash_profile calls X.

you should probably check out /.bash_profile

the multiple terminals started with root are started by inittab, check /etc/inittab

Well,
I tried doing dsl-hdinstall for multiusers and singleuser and I found the difference in /etc/inittab:

for singleuser with autologin:
< 1:12345:respawn:/bin/bash -login >/dev/tty1 2>&1 </dev/tty1
< 2:234:respawn:/bin/bash -login >/dev/tty2 2>&1 </dev/tty2
< 3:234:respawn:/bin/bash -login >/dev/tty3 2>&1 </dev/tty3
< 4:234:respawn:/bin/bash -login >/dev/tty4 2>&1 </dev/tty4

for multiuser and no autoloin:
> 1:2345:respawn:/sbin/getty 115200 tty1
> 2:2345:respawn:/sbin/getty 115200 tty2
> 3:2345:respawn:/sbin/getty 115200 tty3
> 4:2345:respawn:/sbin/getty 115200 tty4

I haven't tried this myself. Let me know if you find out anyhing.

This is my understanding of how DSL's autologin works:

The /etc/inittab specifies that the root user should be automatically logged in

Code Sample

1:12345:respawn:/bin/bash -login >/dev/tty1 2>&1 </dev/tty1

If the runlevel is equal to 5 (the default runlevel) it then switches to the 'dsl' user as specified in /.bash_profile:

Code Sample

#!/bin/bash
RUNLEVEL=`runlevel|cut -f2 -d' '`
if [ $RUNLEVEL -eq 5 ]
then
export HOME=/home/dsl
cd $HOME
while [ 1 ]; do
su - dsl
done
fi

The X Windows System is started as specified in /home/dsl/.bash_profile (this file originally resides in /etc/skel and is copied to /home/dsl/ by dsl-config).

Code Sample

#!/bin/bash
export IRCNICK=DSL
SSH=`env | grep SSH_CONNECTION`
if [ -z "$SSH" ]; then startx; fi
