rc(1) says:
rfork [nNeEsfFm]
Become a new process group using rfork(flags) where
flags is composed of the bitwise OR of the rfork flags
specified by the option letters (see fork(2)). If no
flags are given, they default to ens. The flags and
their meanings are: n is RFNAMEG; N is RFCNAMEG; e is
RFENVG; E is RFCENVG; s is RFNOTEG; f is RFFDG; F is
RFCFDG; and m is RFNOMNT.
this sounds to me
rfork
is equivalent to
rfork ens
or am I misunderstanding?

yes. it also agrees with the source code.
