It is the only mandatory option (sic). Kernels with no options (although they might not be useful) can be built except for this bug. Example of a minimal config file (before misconfiguration of the configuration of scheduling). %%% machine i386 cpu I686_CPU ident MIN %%% BTW, a minimal kernel is now almost 3 times as large as in FreeBSD-2 due to general bloat and misconfiguration of configuration in the opposite way (subsystems much larger than scheduling are standard; you can still leave out FFS and INET but many less useful subsystems are standard).
