Tested on both selinux and non-selinux systems, current trunk appears
to work fine. I like how you changed the codepath to disable_execute,
your solution allows to keep it static.

Just one thing I noticed: why do you need to re-read sudo.conf in sesh?
This could possibly be an issue, depending on when the selinux domain
transition happens. If sesh already runs in the target context, then
selinux might block access to the conffile. The code doesn't seem to
fail on EACCESS (as I read it), so it will be fine and can be solved
with a dontaudit selinux rule -- but I'm still curious :)

Many thanks for your help,
