 * `org.zfsbootmenu:commandline` set the list of kernel commandline options to be passed to the final OS. Do not set `root=`, this is set for you.
 * `org.zfsbootmenu:active` controls whether boot environments appear in or are hidden from ZFS Boot Menu:
   - If a boot environment has the property `mountpoint=/`, set `org.zfsbootmenu:active=off` to *hide* the environment. For any other value, including not set, the boot environment will be shown.
-  - If a boot environment has the property `mountpoint=legacy`, set `org.zfsbootmenu:active=on` to *show* the environment. For any other value, including not set, the boot environment will be hidden. **Note**: Not all Linux distributions support booting from datasets with `mountpoint=legacy`.
-* `org.zfsbootmenu:rootprefix` controls the prefix added to the name of the ZFS dataset provided as the root filesystem to kernels booted by ZFSBootMenu. For example, a command-line argument of "root=zfs:zpool/ROOT/OS" has a root prefix of `root=zfs:`, which is the default value unless the boot environment appears to be Arch Linux; for Arch, the default root prefix is `zfs=`. Set `org.zfsbootmenu:rootprefix` on any boot environment or its parent to override this default. Remember to include any necessary delimiters, like `:` or `=`.
