Ok.

Oh, I had a really great understanding problem. Overlays are not
scripts... shame on me.

ok, now, I think I understand.

I think, and hope my livecd-stage2 is generic based...

have it.

forgot it.

I'll try that.

Of course.

The only one I found myself ;-)

Sure.

Ok, it's more clear now.

I was talking about creating X configuration etc... that is only possible
during boot. But you already answer to that.

of course.
I tried that, and I have something very strange.
I'm not very good at shell scripting, but when I see that, I don't find it
really normal :
livecd ~ # cat /root/.bashrc
#!/bin/bash

if [ -x /usr/bin/X ]; then
        if [ -e /etc/su - chris -c startx ]; then
                rm -f /etc/su - chris -c startx
                su - chris -c startx
                cat /etc/motd
        fi
fi

"-x /usr/bin/X", I understand, but what is that :
"-e /etc/su - chris -c startx" ???
My livecd/users is "chris"

Of course, I always have an error at boot :
.bashrc: line 4: [: too many arguments

of course. clear.

I only do that, I read it, I read it, and I read it again... I learn it ;-)

I found this solution too, but if I don't use xdm, what will execute X ?


Thank you for all your help even if you can't understand all what I mean ;-)
