[bin] 13# 14# KMOD The name of the kernel module to build. 15# 16# KMODDIR Base path for kernel modules (see kld(4)). [/boot/kernel] 17# 18# KMODOWN KLD owner. [${BINOWN}] 19# 20# KMODGRP KLD group. [${BINGRP}] 21# 22# KMODMODE KLD mode. [${BINMODE}] 23# 24# LINKS The list of KLD links; should be full pathnames, the 25# linked-to file coming first, followed by the linked 26# file.
