Re: RPM deltaing tool

[Leonard den Ottolander <leonard den ottolander nl>]

Hello Michael,

> xdelta uses small block sizes so splitting up files is unlikely to help.

That seems to be correct. Testing this on
kernel-2.4.22-1.2115.nptl.i686.rpm and 2149 renders a g(/b)zipped tar of
deltas that is even slightly bigger (+ < 50K) than the cpio.delta.

By the way, this deltaing works very nicely on kernel.src.rpm (deltas
totaling < 320K on 32M (< 1% !), probably due to identical
kernel.tar.gz, so I guess this will be true for any src.rpms with
identical tarballs) and kernel-source.rpm (< 900K on 40M).

Bye,
Leonard.
