Is it possible in a supported way, (or will likely be added), to share a boot device with SLOG?
The answer is no.
The reason is simple. iXsystems developed / is developing TrueNAS, (Core & SCALE), for the Enterprise Data Center market. That market requires reliability more that cost saving features of shared function storage devices.
This idea comes up several times a year, (more so since TrueNAS SCALE was released). And the answer has not changed.
