There’s already a way to turn onehit on/off via the command-line -c option (man
rt):
rt -c "set a_onehit=0” ...
I also just added support for -c “set a_no_booleans=1” too, so that can be
tested independently. We’re not consistent yet, but there is a desire to push
features related to devs and debugging to the more verbose -c interface. With
a couple notable exceptions.
Cheers!
