Ah ha !   Once again you save me from head scratching and confusion.

     Looking at :

         # grep -i 'riscv' /usr/src/Makefile.inc1
                         riscv64/riscv
         .if ${TARGET} == "riscv"

That did not help me very much with the syntax that poudriere wants.

# idprio 0 poudriere jail -c -j 150rv64 -a riscv.riscv64 -b -m 
src=/usr/src -f rv64/poudriere/jails/150rv6

Thank you very much once again :)

In unrelated areas I have been giving a considerable stare at the P550
but figure it is best to await folks with far more skills than I to
attack that unit.

     https://www.sifive.com/cores/performance-p550

My guess is that it would do everything the Unmatched Rev B can do with
the added SATA port there for serious convenience. The absent M2 SSD
slot is a bit strange but who knows. It does have some sort of onboard
managment port as well as dual ethernet and that is a real bonus.
