For the purposes of this entry they can be used interchangeably to designate a version of Linux specific to Fermilab.

Fermi Linux started out as an extension of the PC Farms Pilot Project spearheaded by Connie Sieh.

Continuing to update the SGI and AIX hardware for the computing needs of that experiment was very expensive.

This includes dedicated email lists and regular meetings provided by the Scientific Linux development team.

Workers in Fermilab took the source code from Red Hat Enterprise Linux in srpm form and recompiled them resulting in binaries in rpm form with the only restrictions being the license from the original source code.
