Ehm, to boot my Devel-Workstation you need definitivly ROOT rights!
To change passwords you need root access too AND KEY access to my
PostgreSQL server.

This works only if you have at least TWO computers!

OK! -  Again:

My Devel-Workstation has

sda     dom0    Master System which boot up

sdb     domU    Running Debian GNU/Linux Unstable  (Sid)
sdc     domU    Running Debian GNU/Linux Testing   (Etch)
sdd     domU    Running Debian GNU/Linux Stable    (Sarge)
sde     domU    Running Debian GNU/Linux OldStable (Woody)
sdf     domU    Running RedHat
sdg     domU    Running SuSE/Novel

the later two are only started at manual request...

My current Devel-Workstation starts serial 4 xservers in chroots for the
four Debian releases.

In a previously message (last year) there was someone which told me, I
can not run several "Virtual Workstations in the domU since they do not
know WHO should handel the Graphic-Card.

Idealy I want to start (like in the four chroots) 4 xservers on :0, :1,
:2 and :3.

Since I can boot ALL 6 installations directly from my LILO menu they are
fully working installations.  I have manged to start the Xen System
using LILO and kexec...  OK it works but the X-Server do not coming up.

Since I have only one computer, I have setup dom0 to handel this stuff...
...and start per /etc/inittab and ssh four (root) xsessions which should
start on :0, :1, :2 and :3 four xserver with WDM.

But it does not work...

Please NOTE:  I need to run ALL FOUR releases in parallel for testing of
programs which need direct interaction.

Question:  HOW must I change the following /etc/inittab that four
xservers with WDM are starting up:

# Chroots for Unstable (Sid)
1:2:respawn:/sbin/rungetty  tty1  -u root -g root -- chroot /Chroot-999-sid 
/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty1
2:2:respawn:/sbin/rungetty  tty2  -u root -g root -- chroot /Chroot-999-sid 
/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty2
3:2:respawn:/sbin/rungetty  tty3  -u root -g root -- chroot /Chroot-999-sid 
/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty3
4:2:respawn:/sbin/rungetty  tty4  -u root -g root -- chroot /Chroot-999-sid 
/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty4

# Chroots for testing (Etch)
5:2:respawn:/sbin/rungetty  tty5  -u root -g root -- chroot /Chroot-4.0-etch 
/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty5

# MasterSystem
21:2345:respawn:/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty21
22:2345:respawn:/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty22
23:2345:respawn:/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty23
24:2345:respawn:/sbin/getty -f /etc/issue.linuxlogo.banner 38400 tty24

I assume, that I must change the "chroot <directory> " to something like
