FreeBSD Developer Support
~~~~~~~~~~~~~~~~~~~~~~~~~
The --freebsd-option provides a tool you can set special kernel options. This
is a developer tool and should only be used if you are familiar with the
internals of the FreeBSD kernel and what these options do.
The options are listed in:
https://github.com/freebsd/freebsd/blob/master/sys/conf/NOTES
An example to turn on a verbose kernel boot, verbose sysinit and bus debugging
configure with:
--freebsd-options=bootverbose,verbose_sysinit,bus_debug
The LibBSD waf support splits the options and converts them to uppercase and
adds them -D options on the compiler command line.
