zfs-initramfs currently provides extraneous, undesired symlinks to
devices directly underneath /dev/ to satisfy zpool's historical output
of unqualified device names. By including this environment variable to
signal our intent to zpool, zfs-linux packages can drop the symlink
behavior when updating to its upstream or backported output behavior.
