Since a few days we have some severe nfs problems with the server continuously logging "RPC request reserved 84 but used 276" and the affected client blocking. This may be related to the fact, that after the last update of nfs-utils the mount.nfs command now supports nfs4.1 so that new mounts are done with nfs4.1 (or nfs4.2 if the server kernel supports it) and not with nfs4.0 as before. Some bug reports on the internet suggest, that the problem does not exist with nfs4.0 [1]. Change make-automaps to add -vers=4.0 to all location entries of all maps. Experiments confirmed, that this (nfs-specific) option doesn not interfere with bind mounts, when the location is on the local host. [1]: https://bugzilla.redhat.com/show_bug.cgi?id=1552037
