[softwaremgmt] makedeltarpm makes large deltas
I see that to keep up to date with factory I am required to download >1GB on each new sync. I pay for bandwidth so I wanted to create some delta rpms on a weekly basis on a server I have access to which has no bandwidth restrictions (which I could sync to factory). I then planned to update my system from that deltarpm server on a weekly basis for, I would guess, a few 100 MBs at most. My problem is that for example makedeltarpm -vv mozilla-xulrunner181-1.8.1.12-4.x86_64.rpm mozilla-xulrunner190-1.8.99.5-2.x86_64.rpm mozilla-xulrunner.delta yields a delta with around the same size as the rpms. This is true for all those I tried, am I misusing the makedeltarpm program or is this expected, or is this the result of the transition to lzma compression for factory rpms? I am running from the 11.0 alpha3 64bit CD with some packages updated to factory (eg, zypper, yast), deltarpm = 3.4 ____________________________________________________________________________________ You rock.

The reason is that we switch the RPM payload format between 10.3 and 11.0 and you might see a fallout of this now. Ciao, Marcus -- To unsubscribe, e-mail: opensuse-softwaremgmt+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-softwaremgmt+help@opensuse.org

Also, lzma is not even supported yet, so your deltas won't work at all.
