While one could set options in the kernel to affect the ufs.ko build, there’s not a universal ufs.ko that can be loaded easily that switches between the different types of options. You can create modules that do this, but that’s a very very different problem than the one I want to solve, namely you get the same[*] functionality having device fred in the kernel config as kldloading fred.ko. So rather than bite off that problem also, I’m opting for simplicity. >> +options SOFTUPDATES # Enable FFS soft updates support >> +options UFS_ACL # Support for access control lists >> +options UFS_DIRHASH # Improve performance on big directories >> +options UFS_GJOURNAL # Enable gjournal-based UFS journaling >> +options QUOTA # Enable disk quotas for UFS > >> +options SYSVSHM # SYSV-style shared memory >> +options SYSVMSG # SYSV-style message queues >> +options SYSVSEM # SYSV-style semaphores >> +device agp # support several AGP chipsets >> +device random # Entropy device >> +device padlock_rng # VIA Padlock RNG >> +device rdrand_rng # Intel Bull Mountain RNG >> +device vlan # 802.1Q VLAN support >> +device tun # Packet tunnel. >> +device gif # IPv6 and IPv4 tunneling > > This is loadable too.
