That is true. You either have to be very careful and re-IPL the guests, or purchase something like Levanta from Linuxcare.

Hi all - Let me begin by saying I am still very new to z/VM. I am a Linux guy, not a mainframe fellow, so bear with me if I ask silly questions. We are considering using one chunk of DASD space to install RHEL 3 and then having multiple guests access /usr, /bin, /sbin and so on read-only. That way we apply updated RPMs to the "master" all the read-only guests will be updated as well. The sticking point is that it seems that the read-only guests have to re-access the DASD before they see the updates that have been applied. Am I understanding this correctly? To me this sounds very problematical. In Linux/Intel, when a new RPM is installed, in most cases it simply involves restarting the updated service for the new software to be used. In z/Linux it seems that a simple update of code will require each guest to re-IPL in order to access the read-only DASD of the "master" image. Can someone clarify this for me?
