Since CentOS is an rpm based system you will almost always be rebuilding from srpms and *not* from plain tar balls. Repos catering for RHEL/CentOS/Fedora provide srpms by default. However, if you want to make your own (s)rpms or patch existing ones you will indeed need a "classical" build environment to do so. And since there are a couple of packages that mock will not build you will need a fallback build environment for such cases. Regards, Leonard. -- mount -t life -o ro /dev/dna /genetic/research
