feature: make yum use rsync to minimize data download
Last modified: 2014-01-21 17:53:52 EST
Description of problem:
If yum could be integrated with rsync, the amount of data downloaded for updates
could be minimized.
For example, if the users machine already has kernel-xxx.rpm sitting in
/var/cache/yum/, and yum determines that a new kernel (kernel-yyy.rpm) is
available as an update, allowing rsync to analyze kernel-xxx.rpm to see the
similarities to kernel-yyy.rpm may well reduce the actual amount of data
required to create kernel-yyy.rpm on the local system.
if ( package_update_available )
if ( cached_version_of_package_on_local_box )
/* rsync "/var/cache/yum/old_package_version.rpm" against
/* download as normal. */
Version-Release number of selected component (if applicable):
Steps to Reproduce:
rsync is not a good idea for mirrors, if nothing else.
