This relates to an old PR (122127) It appears you can set the unit of a ppp profile under rc.conf with something like below. This isnt documented anywhere as far as i can see, and I had to work it out by reading the ppp rc script. Thats fine for me but not many others An example in the /etc/default/rc.conf and in the handbook would be very useful eg ppp_enable=yes ppp_profile=test ppp_test_unit=0 <<<<< no docs
Updated 10.1-BETA and 10.1-RC versioned bugs to 10.1-STABLE.
Closing since the man page seems to have this information. It looks it's been there since 2008. Please reopen if I'm missing something. From man rc.conf ppp_⟨profile⟩_unit (int) Set the unit number to be used for this profile. See the manual description of -unitN for details.
