I am modifying /etc/security/limits.conf on the machine, and then installing Supervisor in a Chef recipe. After the recipe run finishes, if I run cat /proc/<process id>/limits I see:

Limit                     Soft Limit           Hard Limit           Units     
Max cpu time              unlimited            unlimited            seconds   
Max open files            1024                 4096                 files

If I log into the machine and run service supervisor restart, the max open files is then set correctly. However, if I run this command in the recipe (right after installing supervisor, at the very end of the recipe, anything) the limit does not change. It is not until I log in and manually run that command that the limit changes.

How can I get the open file limit for supervisor to change using the chef recipe? Operating system is Ubuntu 12.04.

To any weary googlers: you might be looking for the minfds setting in the supervisor config. This setting seems to take effect for both the supervisord process as well as the children. I had a number of other strategies, including launching a shell script that set the limits before executing the actual program, but this was the only thing that worked.
