What does rctl report? (Not that I've ever used RACCT/RCTL.)

# rctl
rctl: RACCT/RCTL present, but disabled; enable using kern.racct.enable=1 tunable

From what I read in man rctl, "jail" is one of the "subject" categories and
"datasize" is one of the "resources". So it looks like rctl is one of the ways
a specific limit could be imposed.

I'm guessing you would look/control from outside the jail.
