request-key — handle key instantiation callback requests from the kernel
/sbin/request-key <op> <key> <uid> <gid> <threadring> <processring> <sessionring> [<info>]
This program is invoked by the kernel when the kernel is asked for a key that it doesn't have immediately available. The kernel creates a partially set up key and then calls out to this program to instantiate it. It is not intended to be called directly.
All errors will be logged to the syslog.
