Autofs fails when specifying 'vers=4.0' or 'vers=4.1' in /etc/auto.master

Solution In Progress - Updated -

Issue

  • autofs map entry options field does not accept dot character
  • The lexer pattern for the options string does not accept the dot ('.') character, so setting an NFSv4 minor version with 'vers=4.0' fails as a syntax error.

Environment

  • Red Hat Enterprise Linux 7
  • Autofs
