Subject: If mount.nfs is not installed setuid, an attempt to perform a "user"
X-Git-Tag: nfs-utils-1-1-3~45
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=0930b25ee3a1eb28b957cdc70c9a1958812d895f;p=nfs-utils.git

If mount.nfs is not installed setuid, an attempt to perform a "user"
or "users" mount will fail with a fairly obscure error message,
typically about getting "permission denied" from the server.

This patch gives a more helpful message in that case.
