User talk:Monsieurp/Gentoo Linux on ZFS

When doing zfs create, use WWNs for persistent block device naming or else grub-probe may have trouble. This is especially important when wanting to USE=libzfs with GRUB and to boot with root on ZFS. You can find the World Wide Names by looking in /dev/disk/by-id/. sys-boot/grub-2.02-r1, sys-fs/zfs-0.7.12, December 2018.
