FC9 sudo sudoers env_reset

[SteveT]

Under fc4/fc6 I can sudo and keep the original users environment ok. Under FC9 it appears that the environment is reset to a basic level and this appears to be dependent on env_reset.
The problem is that I can't see how to turn env_reset off. It says that env_reset is the default - but the parameter env_reset doesn't take any arguments - so how do I stop it being the default?

Does anyone know who makes the distro for FC9?

I found this link:
http://markmail.org/message/dpyivs3nimzykdir

that seems to imply that the 1.6.9p13 release was compiled with secure_path set. This seems to always then reset PATH to a fixed set of directories, irrespective of what other settings you have in the sudoers file (I have !env_reset and have added PATH to env_keep - as well as trying sudo -E with setenv set in the defaults.

So can anyone tell me how I keep PATH set - or if it is not possible to keep PATH when sudo is compiled with secure_path can I ask why the package is compiled with that option (as it then seems impossible to keep the PATH with the options in sudoers - and surely the options are there to allow the user tio configure different behaviours?).
