Delta ISOs

System Requirements in Fedora

RPM packages in Fedora 12 and later use xz compression (older versions use gzip-compressed RPMs). In order to either create or use deltaisos between ISOs containing xz-compressed RPMs, Fedora 11 or later is required. Fedora 10 or below will not work since their version of the deltarpm package does not contain xz support. In addition,

• In Fedora 11, the deltarpm package must be the updated version, 3.5 or later (not the deltarpm-3.4-16.fc11 release version which does not contain xz support).
• In Fedora 12 or later, the deltaiso package must be installed as well. (In Fedora 11, deltaiso support is contained in the deltarpm package, and there is no separate deltaiso package.)
