34 To enable a feature on a pool use the
37 .Sy feature Ns @ Ns Ar feature-name
41 .Sx Compatibility feature sets
55 Every feature has a GUID of the form
56 .Ar com.example : Ns Ar feature-name .
57 The reversed DNS name ensures that the feature's GUID is unique across all ZFS
64 Each supported feature also has a short name.
65 By convention a feature's short name is the portion of its GUID which follows
70 .Ar com.example : Ns Ar feature-name
72 .Ar feature-name
74 however a feature's short name may differ across ZFS implementations if
