[CTX] [ALL] external privileged commands
Privileged operations without being superuser
Some operations of DeleGate needs the privilege of super-user, but running whole DeleGate process under super-user's ability is not desirable for security. To solve the problem, you can execute DeleGate by normal user while executing a privileged operation by a small external program with "set user ID on execution" flag. Those external subsidiary programs are placed at DGROOT/subin/ by optional installation.
