sparc64 snapshots, run inside an LDOM. Primary domain and the other 6 LDOMs
are 6.1-STABLE.
I've put the snapshot LDOM through some paces with each snapshot: high CPU
load, networking, and heavy filesystem utilization. It's every bit as solid
as the other LDOMs. I have only seen the "relinking" message at the end of
snapshot upgrades, but due to /bsd changing upon each reboot, I believe it
is behaving exactly as Theo described.
Right after last snapshot update an hour or so ago:
MD5 (/bsd) = f9a2402b74004054a6118a41fc4cd310
MD5 (/bsd.booted) = c5ef22ec29b1a1a7a087821bab82361a
MD5 (/bsd.rd) = e897b04724b2238845a4835c276c09ee
MD5 (/bsd.sp) = 7c7672b16e08c7286dd7b2bd6855c6a2
A reboot a while later shows it did, indeed boot from the new kernel and
put yet another random one in place for next time.
