What is SLI?
Scientific Linux IFIC is the current official linux operating system at IFIC. It has been developed based on CERN's SLC, which has been modified in order to adapt it to the institute requirements and remove CERN specific configurations which are only useful at CERN environment. In turn, SLC is based on Scientific Linux, which emerged from Redhat's RHES.
In sort: RHES, —> SL, —> SLC, —> SLI.
