Subject: [PATCH] file-systems: Set default value of the check? field to #f for
 NFS.

Network file systems do not need to be checked locally, so provide a better
default value.

* gnu/system/file-systems.scm (<file-system>): Make the check? field thunked,
and compute the default value based on its own type.
