My understanding is that this is part of Oxide's secret sauce.
Is there much traction with this elsewhere? I worked at SunOS and Solaris shops in the past, and remember telling my boss that this new Linux thing was going places and she dismissed it as nonsense.
Oxide uses illumos under the covers That's in no small part due to the composition of the early team--but we have benefitted tremendously from features (ZFS, SMF, FMA, Zones, bhyve, etc.) and observability infrastructure (DTrace, mdb, libproc, etc.) folks on the team have worked on for decades.
