#10 /etc/umlutil/xserver fails if passed UML_X??? parameter

[Anonymous]

Passing UML_XARGS or UML_XFULLSCREEN in the "control
start' command line causes the /etc/umlutil/xserver
script to fail to start Xnest_static
Running /etc/umlutil/xserver from the command line in
one of the console windows gives
[root@redhatadvancedserver21 root]# /etc/umlutil/xserver
Unrecognized option: -geometry 1280x1024+0+0

This is with
[root@redhatadvancedserver21 root]# cat /proc/cmdline
initrd=.initrd-2.4.19-5um umid=redhatadvancedserver21
ubd0=rootfs root=/dev/ubd0 ubd7=swapfs mem=256m
eth0=tuntap,,fe:fd:17:a3:5c:69,140.83.22.195
UML_XDISPLAY=140.83.22.195:0.0 UML_XFULLSCREEN=true

although the issue is the same if I do
control start UML_XARGS=-geometry@1024x768+0+0

All the individual parts of the script work from the
UML command line, and I can do 'Xnest_static -geometry
1024x768+0+' at the command line, but running the
script as a whole causes the Xnest startup to fail.
