See Delta ISOs for instructions on using deltaisos. Some of the larger deltaisos listed below have been broken into several parts using the split command. This is due to the limitations of the file hosting services being used - file size limits, inability to pause/resume downloads, or unreliable downloading. (For example, downloads may occasionally fail in the middle - if this happens, try again.) After downloading all parts, and verifying the checksums, combine them using the cat command. For example,
cat Fedora-12_13-i386-DVD.diso.? > cat Fedora-12_13-i386-DVD.diso
Experimental zsync control files may also be available. Zsync is not currently available in the Fedora repos, but is available as a source tarball from the developer's website. RPMs and even yum repositories can also be found, for example here. Note that if this particular repo is used, then a line
includepkgs=zsync
should be added to network.repo, to prevent any other packages from this repo (many of which already exist in the Fedora repos) from being used.
