tested on FreeBSD 12.1
We are here adding ZFS to the MINIMAL template, as FreeBSD XEN/PVH doesn’t have a loader hence doesn’t know how to load modules (and zfs.ko
is a module).
cd /usr/src/sys/amd64/conf/ cp -pi GENERIC GENERIC-ZFS cp -pi MINIMAL MINIMAL-ZFS vi GENERIC-ZFS vi MINIMAL-ZFS options ZFS #config MINIMAL-ZFS #cd ../compile/MINIMAL-ZFS/ #make cleandepend && make depend #make > /root/kernel.log && echo BUILT cd /usr/src/ dmesg | grep cpu ls -lF /etc/make.conf #noexist echo NO_MODULES=1 > /etc/make.conf time make buildkernel KERNCONF=GENERIC-ZFS > /root/kernel.log && echo BUILT make installkernel KERNCONF=GENERIC-ZFS > /root/kernel.install.log && echo INSTALLED ls -lhF /boot/kernel/kernel strings /boot/kernel/kernel | grep -i zfs
