Summarizing a conversation from the team meeting: There is no need to reject a `sched.expiration` update that overlaps with existing reservation (job or future DAT or downtime reservation). Since this...

A WIP PR with flux-core support for updating the duration of running jobs is in flux-framework/flux-core#5522. It contains the implementation of the sched.expiration RPC to request the expiration update from...

Update: flux-framework/flux-core#5522 was merged and released with flux-core v0.56.0. Until this issue is resolved, updates of running jobs will be allowed without notification to the Fluxion scheduler, which will have...

> My instinct is to go with https://github.com/flux-framework/flux-core/pull/5184 -- or something similar -- in the long run as Perlmutter has a lot of nodes, so it might be a significant...
