I'm new to posting, however, i do read the list :)
John's comment about the short support lifetime of FC raises one of my
concerns about distros and cluster set-ups in general. In my
department we have RH/FC based clusters. When purchased they came
with a pre-installed distro and have pxeboot/images. I then spent
time tuning them to our needs.
My questions relating to this are:
i) Is the practice of buying clusters with pre-installed distros popular?
ii) Would it be better to develop our own installation process for
clusters so that upgrades, in terms of distros, can be rolled out
easily? I feel like i'm tied in some way to the supplier of our
cluster for upgrades.
iii) Do people regularly upgrade their clusters in relation to
distros? I guess this is like asking how long is a piece of string
because everyone's needs are different.
Apologies if this sounds like a strange first post :)
