Hello, My tip: do not waste time, use a Debian as build platform for Unattended. (a VM with 8GB of disk is fine).
I've spent hours in order to use CentOS4 as a build platform for Unattended but I was unable to maintain it working on a long period. It's too difficult to deal with glibc of the system, that is more/less used while building for instance. my $0.02 - Pierre Le 28/04/2011 23:02, Timothy J Massey a écrit : > Hello! > > I am trying to compile the linuxboot ISO on CentOS 5.
