To put a fix in F8, you version it pkg-1.fc8.1 *not* pkg-2.fc8.

That doesn't work if it's a new version.

That's a great argument for not bumping package version (rather than release) too much!:

In F9 before F10 final is frozen, any package version bumps must be reflected in rawhide/F10 too (by current policy in the existing EVR script, ignoring strange stuff like epochs making the base version number irrelevant), so people are free to bump versions without using the above technique.

Only after F10 is frozen would the above technique be required, and prohibit verion bumps. I'd argue that by that time, it'd be good policy to disallow version bumps in F9 anyway, since any requirement for a version bump that didn't exist in the first ~5 months of a release doesn't exactly seem to qualify as maintenance; instead significant new stuff should be in the new/latest distro release.

If something like the above is not the policy, how are CD/preupgrade upgrades possibly going to be reliable? An upgrade would end up installing whatever random subset of Fn was newer than Fn-1. Whilst I appreciate that a "yum update" after the upgrade would solve the issue, that fact doesn't address what happens when running rpm scripts during the install against a random mix of Fn/Fn-1, nor how the system is supposed to sanely boot with the same random mix before the yum update.

This technique is useful, but to prevent dist-f8-updates > dist-f9-updates situations (which are true packaging errors), not dist-f8-updates > dist-f9 situations (which are normal). If you push a new version to F8, you have to push it to F9 too, but it'll be only in dist-f9-updates, not in dist-f9. Only packaging-related issues which don't affect F9 should be fixed in F8 with the n%{?dist}.1 trick.
