I haven't been able to get the 6.X kickstarts to work without a video
card present. I haven't tried with 7.X, but 5.X seemed to work. Probably
not a big deal if you're only going to install once. I install often and it
me very grumpy.
Like you, installing makes me grumpy too, so I try not to do it
more than once. Ideally all of our compute servers would share
the same (network) file system. There are ways of doing this
now (typically via NFS) but they tend to be hand-crafted and
In particular, I notice that the recent Scyld distribution
assumes that files (libraries if I remember rightly) will be
installed and available on the local computer.
Why do people want to install locally? (Scyld people in particular
are encouraged to reply.)
And there's a related problem (to installing) which we might call
"updating" in which, for example, I am running RedHat 6.2 now and
I wish to rip it out and install RedHat 7.0, but I also want to
preserve all(?) of my local changes.
Let's make the simplifying assumption that whenever I install a
RedHat distribution I always install everything (it's less than
2GB which is hardly worth worrying about, particularly when
shared amongst a bunch of computers, and there's a RedHat installation
menu option that makes selection of "Everything" straightforward).
Anyone solved this updating problem in the context of a single
file system shared by multiple computers?
And to you Robert Brown: speak for yourself please when you say
(in your message of Sun, 3 Dec 2000 16:03:39 -0500 (EST)):
A beowulf is a high performance computing
cluster, not a data or web server cluster.
This kind of supercomputer elitism, this fascination with fine-
grained parallelism and linear speed-up has held back the progress
of single system image multicomputing for long enough. I disagree
with your claim, so much so that I wouldn't even fight for your
right to make it (well, not with much conviction).
