PKGDELTA(8) Pacman Manual PKGDELTA(8)NAMEpkgdelta - package delta generation utility
SYNOPSISpkgdelta [options] <package1> <package2>
DESCRIPTIONpkgdelta is used to create package delta files between two versions of
the same package. These files are essentially binary patches. pacman(8)
can download deltas instead of full package upgrades, and use them with
the previous versions of packages (in the package cache) to synthesize
the upgraded version of the packages. This likely reduces download
sizes for upgrades significantly.
pkgdelta requires xdelta3(1) to do its job.
Only create delta files if the delta is smaller than ratio *
package_size. Possible values: 0.0 to 2.0. Recommended values: 0.2
to 0.9. Default value: 0.7
Minimal size of the package file in bytes to be considered for
delta creation. Default value: 1048576 bytes = 1MiB. This may be
any absolute size in bytes, or a human readable value such as 4 MiB
Be quiet. Do not output anything but warnings and errors.
