that's a very good hint actually!

i am in the process of doing that. but i gives me unneccessarily a
hard time, which disappoints me. the whole thing is designed more for
dummies then for people which most of the time know what they are
 i could live with the fact that it's not documented where actually the
rpm's and install scripts are "hidden" on the CD, i also would survive the
fact that the dependencies of the rpms are not ok on my SuSE systems, i
could also live with the fact, that the startup scripts are RH dependent,
but... it assumes fixed and redhat specific mount points for the CD, it
assumes that the CD is mounted on the same computer as the machine where I
want to install it (i have the CD popped in my SUN or maybe my 2000 or
whatever desktop and the data center is somewhere else) , it assumes
everything below /boot follows RH standards, it assumes, it assumes .....
finally, as you indicated.... it's some effort! well, sooner or later i'll
figure that out, since there are only shell scripts and Makefiles for that

my point: why couldn't this stuff designed in a more compatible way?
it IS possible to compile a kernel, 2nd party drivers like qlogic, oss or
e1000, independent on the brand of Linux installed.

my suggestion would also be: if DELL would really opensource the
openmangement tools, the combination of efforts would result in a
better product, which is not only a benefit for the costumers but also
for DELL, since it saves service time. currently if a have a service
case on our 128CPU+ cluster, a lot of time is being spend on both sides
tracking down what the actual problem is.
