New: Have spindle parse mounts (and other data sources as needed) to determine what directories are shared, what looks like a tmp directory, etc. Could add errors that "TMPDIR is not plausible". Corner cases: rare startup mode fork+exec off of server by seeing who can get an exclusive lock in the TMP directory (spank plugin does this). Don't want to have multiple ranks on a single filesystem appear to be multiple nodes. (Friday, May 8th)

Along these lines: DEFAULT_LOCAL_PREFIX assumes that everything underneath a prefix is local, but there are cases where global mounts might end up in there. A better approach is to have Spindle track mounts, not prefixes, and understand which mounts are local and which are global. 17 July 2026.
