 Notice several options that you should consider using:
 
 | Setting | Description |
 | ------- | ----------- |
-| `nobootwait` | Don't halt boot process waiting for this mount to become available
+| `nofail` | Don't halt boot process waiting for this mount to become available
 | `lookupcache=positive` | Tells the NFS client to honor `positive` cache results but invalidates any `negative` cache results. Negative cache results cause problems with Git. Specifically, a `git push` can fail to register uniformly across all NFS clients. The negative cache causes the clients to 'remember' that the files did not exist previously.
