Subject: mount: silently fails when bad option values are given
X-Git-Tag: nfs-utils-1-2-3-rc4~11
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=740171dea45a57e396a86fbda1579a465f101854;ds=sidebyside

mount: silently fails when bad option values are given

mount.nfs should not only fail when an invalid option values
are supplied (as it does), it should also print a diagnostic
message identifying the problem
