This is my file console.perms: is it correct??

# /etc/security/console.perms
#
# This file determines the permissions that will be given to priviledged
# users of the console at login time, and the permissions to which to
# revert when the users log out.

# format is:
#   <class>=list of regexps specifying consoles or globs specifying files
#   file-glob|<class> perm dev-regex|<dev-class> \
#     revert-mode revert-owner[.revert-group]
# the revert-mode, revert-owner, and revert-group are optional, and default
# to 0600, root, and root, respectively.
#
# For more information:
# man 5 console.perms

# file classes -- these are regular expressions
