Re: [PLUG] how to get sudo to preserve LD_PRELOAD

[TuskenTower <tuskentower@gmail.com>]

Dan,
 Can you do a diff of your environment variables?
   env | sort > my_env.txt
   sudo env | sort > root_env.txt
   diff my_env.txt root_env.txt

 Where are you modifying/setting the LD environment variables?  Last
time I remember playing with those, I edited the linker script to
secure a class project.

 Have you tried removing those lines from the sudoers file?
