at files and permissions

[Brandon S. Allbery]

As quoted from <669 at lzaz.ATT.COM> by hutch at lzaz.ATT.COM (R.HUTCHISON):
+---------------
| About "at" requiring "root" permission, I guess it needs it to write
| into the "atjobs" directory.
+---------------

at needs root permissions so it can setuid() itself to the owner of the at
job file, so it can execute the job as the user who submitted it.
