I was just considering what it might take to IPL from
a network server instead. Granted, this would likely only be to IPL
Linux. And I guess something like this could be emulated by
booting PXE
compatable software from a DVD on the HMC. I was just
thinking that this
might be an interesting way to "bootstrap" a Linux installation
environment.
John, I'm curious as to just what you were thinking about how
this would look/work. Just for creating an install server
instance? (As David mentioned, a DDR-based install instance
is coming down the pike.) Something else besides that? I
ask, because there are numerous ways to accomplish booting a
Linux instance without it initially having access to any DASD
or disks at all. You could even create a way to automate
booting from a virtual reader, etc.
I don't know. I was just low on sleep and watching my PC boot in the
morning and the strange thought came into my head. Why do it at all is
another question. I doubt that anybody would really want a "Linux on
System z thin client", which seems to be what most network boots are
for. On System z, sharing a R/O filesystem would likely be much better.
I wouldn't say, "thin," it would apply similarly in clusters and
anywhere else where one needs lots of computers essentially the same.
It's just the most common use is with thin clients.
And, sharing ro filesystems will become more important on peecees too,
now Intel and AMD have figured out multicores and virtualisation.
