Subject: mount.nfs - make sure program name in error message is correct.
X-Git-Tag: nfs-utils-1-1-0-rc1~26
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=b8b6a251c372b134e66d0f436bf2c6231cc1c055;p=nfs-utils.git

mount.nfs - make sure program name in error message is correct.

getopt_long uses argv[0] in error messages.  So it it is given
argv+2 for example, we need to make sure that argv[2] has the
correct program name.
