VERSION (and LINKEDIT's LISTPROG command) show what capabilities the PROGRAM
requires to run. These are checked by the loader to make sure that group and
account have the necessary capabilities as well. The capabilities that you
can assign to a program are limited to IA,BA,DS,MR,PM,PH.

In this case, the program is doing its own further checking to make sure the
user has specific capabilities that the writer's of the program deemed
important.

With inetd, even a user with SM capability cannot kill inetd. It appears to
be hardcoded for MANAGER.SYS.  My guess would be that it started as source
from UNIX that was programmed to look for root user (or UID 0) and chose to
replace it with the closest MPE equivalent of MANAGER.SYS or UID 1.
