This is neat and all, but I'm not sure I understand how it's better than 'less /var/run/dmesg.boot'? Which is not to say that this doesn't have any merit, I just don't understand it.

Hot-adding CPUs after boot? Not theoretical; I've done this on Linux VMs.
eg. dmidecode -t processor -t cache

So you can do:
dmidecode -t processor -t cache
which produces the following output on my system:
# dmidecode 2.11 SMBIOS 2.6 present. Handle 0x0400, DMI type 4, 40 bytes

FreeBSD has dmidecode https://www.freebsd.org/cgi/man.cgi?query=dmidecode So you can do: dmidecode -t processor -t cache which produces the following output on my system: # dmidecode 2.11 SMBIOS 2.6 present. Handle 0x0400, DMI type 4, 40 bytes Processor Information Socket Designation: CPU1 Type: Central Processor Family: Xeon Manufacturer: Intel ID: 52 06 02 00 FF FB EB BF Signature: Type 0, Family 6, Model 37, Stepp…
Earlier quoted context omitted.
am out of date on freebsd, but IIRC you can 'camcontrol devlist'.. openbsd not so much.
this doesn't give fs-on-disk info however
