 #### Policy descriptions ####
 
+Generally speaking most policies when called to create will filter out drives which are readonly or have less than `minfreespace`.
+
 | Policy | Description |
 |--------------|-------------|
-| all | Applies action to all found. For searches it will behave like first found **ff**. For `create` functions it will only apply to `mkdir`, `mkdnod`, and `symlink`. |
-| eplfs (existing path, least free space) | If the path exists on multiple drives use the one with the least free space and is greater than **minfreespace**. Falls back to **lfs**. |
-| epmfs (existing path, most free space) | If the path exists on multiple drives use the one with the most free space and is greater than **minfreespace**. Falls back to **mfs**. |
-| erofs | Exclusively return `-1` with `errno` set to EROFS. By setting `create` functions to this you can in effect turn the filesystem readonly. |

 | ff (first found) | Given the order of the drives, as defined at mount time or when configured via xattr interface, act on the first one found. |
 | fwfs (first with free space) | Pick the first drive which has at least **minfreespace**. Falls back to **mfs**. |
 | lfs (least free space) | Pick the drive with the least available free space but more than **minfreespace**. Falls back to **mfs**. |
