mirror synchronization flags?

[Thomas M Steenholdt]

Hi

Please correct me if I'm wrong, but as far as I know, the fedora tree 
has no built-in semantics for letting other mirrors (perhaps even 
clients) know if they are fully synced or in the middle of a mirroring 
operation.

How about documenting a way to use some sort of semaphore (file) that 
can be checked to make sure that mirroring has finished? Mirrors, 
clients retrieving their data from a certain mirror could then 
check/wait for the mirror to finish or find another mirror in the meantime?
The document could also share a few ideas on what to include/exclude for 
certain types of mirrors, whether (or when) local createrepo should be 
setup and such?

Debian has something like this IIRC, and it makes the mirroring a lot 
less prone to errors. Less chance of unresolved dependencies due to 
half-synced mirror. Less chance of yum (as example) to fail because a 
package specified in the repodata does not exist, stuff like that?

Was something like this an idea or would it just complicate things more 
than need be?
