One could take an existing iso image and sync it with the newer iso. e.g. rsync --progress --partial http://pkg.belenix.org/iso/belenix_0.7.2.iso ./belenix_0.7.1.iso This would pull in only the diffs in the ISO images and I have done this myself. > My suggestion was, since most people download isos with every > release, it may be a matter of just popping your old CD into the > cdrom drive, and downloading the diffs which assemble into > isos locally.

If we rsync the iso images, then the diffs in the ISO bytes get pulled in, instead of a wget of the various files that sit on the ISO. jigdo does have a role to play, though, and I think you should go ahead and try to jigdo-enable belenix, and we can start providing jigdo based downloads as well - it's just a .jigdo file after all. > The amount of stuff packed into each Belenix CD is unbelieveable ! > I did an online upgrade from 2008.5 to 2008.11 on Sat night.

With Belenix, I'm able to upgrade and downgrade within hours (yes, spkg permits us to downgrade too !). This bandwidth constraint is something that the IPS team does not understand (perhaps because they work on gigabit networks all the time). We had tried to get into a conversation, but received condescension and various explanations in return - none of which help bandwidth starved people. > > Bish > _______________________________________________ > belenix-discuss mailing list > http://mail.opensolaris.org/mailman/listinfo/belenix-discuss > http://groups.google.com/group/belenix-discuss >
