"Red Hat Linux 6.0 is/was built and installed using RPM version 3.0. While continuing to remain compatible with pre-existing binary packages, reorganization of the internals in RPM 3.0 permits more reliable package installation. In addition, more flexible configuration during package builds has been achieved while preserving the original design goal of reproducible builds of binary packages from source code...."
"One of the most noticeable new features in RPM 3.0 is disk space checking. Before installing any packages, RPM now ensures that the system has enough free space for all of the new packages which are being installed. If there is not enough free space available, RPM reports which filesystems need more space, and how much."
