--- Comment #6 from Mateusz Piotrowski <0mp@FreeBSD.org> ---
With rc_fast_and_loose=yes,rc(8) on my system stops processing rc services as
early as rc.d/hostid, which calls exit 0. That's before my machine even sets
its hostname properly. As a result, I get a login prompt saying that I've
booted Amnesiac. I cannot even log in because I get "pam_open_session():
Sessions failure".

Technically, we could fix all rc service scripts in base to be compatible with
rc_fast_and_loose, but it feels unreasonable. Firstly, this is going to be an
up hill battle in the ports tree. Secondly, being compatible with
rc_fast_and_loose requires rc service scripts to use unusual idioms like `(exit
1)` to set the return code without actually exiting if sourced.

My recommendation is to remove support for rc_fast_and_loose.
