Has anyone given though to doing mirror updates via a 'push' rather than a 'pull' mechanism ?
The idea itself is nice, but some mirrors need to do the "pull" atspecific moments in time.
Absolutely, I dont see the process as its now, going away in a hurry. However, if we did setup a mechanism for mirrors to sign up for an update push, when there was an update due, and then ask those mirrors to reduce their regular pull-mirroring down to perhaps once every 96 hrs, would many people opt in ?
It address's the issue of just-in-time-pushing and saving excessive b/w and cpu loads caused on the upstream mirros by regular rsyncs. Plenty of people hit the main msync targets 4 - 6 sometimes 8 times a day. The load on this caused by 200+ mirrors is non-trivial. Also, there is an issue that sometimes critical updates dont make it out for hours, since we must wait for mirrors to pull and finish. Push, should, in theory atleast address some of these issues.
Then there is -c issue. Would be nice if some portions of the tree's were run with the '-c' option set, its not something we can even look at with the pull model.
