New Revision: 272025
URL: http://svnweb.freebsd.org/changeset/base/272025

Log:
  Fix thinko that, with two map entries like shown below, in that order,
  made autofs mix them up: the second one wasn't visible in ls(1) output,
  and trying to access it would trigger mount for the first one.
  
  foobar		host:/foobar
  foo		host:/foo
