7d04a0f5e0 Add privileged services

1c4dd05f40 Add 126 to hardcoded stop exits 
> If a command is not found, the exit status shall be 127. If the
> command name is found, but it is not an executable utility, the exit
> status shall be 126. Applications that invoke utilities without using
> the shell should use these exit status values to report similar errors.

e25813c0b2 Remove closelog call 
It's unclear whether closelog is really safe to call in pre-exec
