There's also the side benefit of the kernel being that much faster to rebuild. Get the list with "kldstat". Here for example, we only build a very few of them: $ kldstat Id Refs Address Size Name 1 19 0xffffffff80100000 b0eec0 kernel 2 1 0xffffffff80c0f000 bca8 geom_label.ko 3 1 0xffffffff80c1b000 1350 mfi_linux.ko 4 4 0xffffffff80c1d000 47958 linux.ko 5 1 0xffffffff80e12000 40c3 linprocfs.ko 6 1 0xffffffff80e17000 a14 linsysfs.ko This yields a very lightweight kernel folder, even when retaining the debug symbols: $ du -hs 46M . This is what you want in /etc/rc.conf : MODULES_OVERRIDE=geom/geom_label if_lagg if_vlan linprocfs linsysfs linux mfi/mfi_linux
