Hmmm. strange, as the software I was trying to use is part of fedora's
main (or is it called core?) distro. Check:
http://ftp.surfnet.nl/ftp/pub/os/Linux/distr/fedora/6/i386/os/Fedora/RPMS/system-config-netboot-0.1.41-1.FC6.noarch.rpm
or I must be mistaken that this not part of the fedora project.
Perhaps you can explain it to me, I'm new here.
Because you were having such difficulty reading and comprehending I
thought you would appreciate a turnkey solution or pre-built
distribution. If not, feel free to browse the RHEL manual,
http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/pdf/rhel-sag-en.pdf.

:-) Being a seasoned Mandriva user, now looking into fedora as it's
So you're a short timer!
also a rpm based distro, I wasn't expecting to be pointed to an other
distro that quickly on this list :-).
The first two references are for Fedora. If Fedora Core offered an
LTSP distribution I would have pointed you directly to it. I gave you
the other references because I want people to use GNU/Linux. The
distribution is a matter of preference. Personally, I like Fedora;
others find it too technical.
Perhaps I could try iscsi too, how hard would it be to setup an iscsi
target on my storage server and install a diskless FC6 client on it?
You are the determining factor. Have fun!

Stefan
