[comp.sys.apollo] INPROT, ACL's, and the great system guru in the sky

Well, I am now deeply immersed in the SR10.1 experience. Here it is,
1AM after my second-and-a-half system regeneration from media and
I am still waiting to get a "clean" OS on my hard disk.

WHY did I regen the system twice and a half? One word: ACL'S!!

Did you all know that INPROT has no template files? I'm sure you did
(why just last week someone asked about this), but this is no big deal
if you want to run a wide-open system.

HOWEVER....if you need to have a closed system (like if you are hooking up 
to the Internet or something useful like that) then you are really
pre...er...out-of-luck. Because of the lack of templates, you have no way 
of knowing the correct ACL state of your OS. 

This can present a problem. For example, most UNIX people close
up rights to everything in /dev as a security measure. 
IF, however, you close up an SR10 /dev...well let's just say that 
your OS doesn't work anymore.

Ok...so that's not too much of a problem, right? You can always UNacl dev.

But /sys/subsys/login? INPROT (and ACL too) seems to delete the subsystem
status of this file. Basically that causes problems with CRP. To fix this,
one must have a copy of the file (with correct ACL's and Subsystems) located
elsewhere...preferably on another node...but unfortunately on media if you
happen to try and INPROT the first SR10 node.

WHY ARE THERE NO TEMPLATE FILES FOR INPROT??? They were provided at SR9.7
(as part of the install software), why did they suddenly disappear?  Is there
a chance of getting a template for a closed system sometime in the near
future? 

Knowing just how tightly your OS can be ACL'd shouldn't have to be a hacking
experience. Someone should be able to tell you. Preferablyt the authors of the
OS.....
