FSCK.NFS(8) System Manager's Manual FSCK.NFS(8)
fsck.nfs - Dummy fsck.nfs script that always returns success.
Debian GNU/Linux need this for when the root file system is on NFS:
there is no way to find out if root is NFS mounted and we really want
to do a "fsck -a /".
The exit code returned by mount.nfs is always zero, meaning successful
