Could this also be a path for generic module parameter control? `flux module param-get qmanager....` vs. `flux module param-set qmanager.queue...`

This is great idea @jameshcorbett! I thought about this but didn't know what would be a great way to achieve this. But your suggestion makes a lot of sense. I...

There are several call sites where return codes are not checked: https://github.com/flux-framework/flux-sched/blob/master/resource/modules/resource_match.cpp#L461

There are a few error paths where `errno` is not preserved. We need to save and restore `errno` for library calls (e.g., `json_decref`) being made on the error paths. https://github.com/flux-framework/flux-sched/blob/master/resource/writers/match_writers.cpp#L261

Here is an additional problem: Our DFU traverser concatenate one or more error strings to its `err_message` string member so that the upper layer can use `get_err_message()` to print it....

I want to spend a bit more time for this. Targeting Sep release.

For example, LLNL has a use case where a cluster can consist of two types of compute nodes: one with 4 GPUs and other with 8 GPUs. For some job...

Please look at the behavior of `resource-query` on the jobspec generated from `flux mini run -N 2 -n 2 -c 18 -g 4 --dry-run xhlp > linpack/spec.N2.n2.c18.g4.yaml` > I did...
