This is probably opening up a whole can of worms about the permissions of a lot of files in /etc, but anyway...
Given what the /etc/system file is, and that according to the man page:
$ man -s 4 system
The /etc/system file is read only once, at boot time.

I was surprised to find the permissions on this file set as such:
$ ls -l /etc/system
-rw-r--r-- 1 root sys 2320 Jun 10 22:47 /etc/system
I just don't see any good reason why this file would be world readable. Actually, I don't see any real reason why this file doesn't have permissions of 0400. Is there any reason I can't chmod it 0400?
If it can be changed, does ASET pick this up?
