All these solutions look very straight forward, I actually in the past
have setup my initrd etc. . . on the VM guest (SLES8 EXEC) and executed a
boot as if to install a new guest the hard way. This method works best
for me because I am using LVM and Reiserfs. So the ways mentioned before
would put me at risk with the systemvg, can only have one. etc. . . .
The ultimate solution in my mind is to have IBM address the issue and
create a VM way of booting from a syslinux that provides us the option of
entering single usermode or some other init level. It may be my opinion
but VM needs some work in order to make a Linux on VM solution capable of
supporting mission critical applications.
Easy access to single user mode is a must in AIX, HP/UX, Solaris, and
Linux on IA$$ platforms. It should be a mandatory requirement on the Z/VM
platform as well.

I suppose I am just more lazy, but my approach would be
vmlinx linux007 201 /mnt/tmp
vmlinx linux007 202 /mnt/tmp/usr
chroot /mnt/tmp
...
detach /mnt/tmp/usr ; detach /mnt/tmp
hcp xautolog linux007
Yes, vmlinx is a little bash script that issues the CP LINK command
through hcp, adds the new device to /proc/dasd/devices and issues the
mount.
When the task at hand is more complicated (e.g. install a stable version
of some package) it is nice to have a working Linux server there and not
need to go through the network setup scripts and load the dasd driver.
