svn commit: r285260 - head/sbin/mount_nfs

[Rick Macklem]

Author: rmacklem

New Revision: 285260
URL: https://svnweb.freebsd.org/changeset/base/285260

Log:
  Since the case where secflavor < 0 indicates the security flavor is
  to be negotiated, it could be a Kerberized mount. As such, filling
  in the "principal" argument using the canonized host name makes sense.
  If it is negotiated as AUTH_SYS, the "principal" argument is meaningless
  but harmless.
