Sudo 1.6.8p3 released.
551) New monitor functionality for systems with systrace(4). When tracing
is enabled sudo will fork a daemon that traces the command and
intercepts and execve() calls and allows/denies the call based on
a sudoers lookup. Also updates the command's environment with
the SUDO_* variables if supported by the version of systrace(4).
551) Added support for multiple sudoers file via #include.

that relative paths work correctly in conjunction with wildcards.

This eliminates ordering issues and makes it possible to apply
sudoers Defaults entries before searching for the command.

pete ALL=PASSWD [A-z]*,!PASSWD root
where PASSWD was defined to be /usr/bin/passwd.
This requires the arg parsing to happen in the yacc grammer.
At the very least, commands and args have to become separate
tokens in the lexer.

in addition or instead of the normal one. The best argument for
this so far is to be able to use separate passwords for the

command regardless of what dir it is in if it is owned by the
trusted user.
27) Split the parser into two stages. The first parse checks for
syntax and sets the Defaults options and sets up the
data structures to check a user. The second stage does
the actual user check.
