Some things always change:
- Keep yourself updated: My last three Linux OS server installations were in early 2004; there were two RedHat 9 machines and before that, Mandrake 10. Since then, all RedHat's products have now become commercial, so we're left to use minimally Redhat-supported Fedora. Mandrake has closed down and been renamed Mandriva!
- Fedora Core 5 ships and uses GCC 4.1. Some applications (quite a few of them, eg: Java EE 5 package) that were compiled with an older GCC 3.2 will require compatibility libraries (such as: compat-libstdc++-33, compat-libstdc++-296)
- In Fedora, yum is recommended for package installation instead of rpm.
- In Fedora, yum needs an OS key before it can install or update any package. Key needs to be obtained using:
rpm --import /usr/share/doc/fedora-release-X/RPM-GPG-KEY*
