File and Dir permissions

I am not sure what your ultimate goal is. Why are you so concerned with permissions?
You are playing with fire if you change too many permissions. /etc is a VERY important directory. I know this because I had some sabotage in one of my boxes. /etc was messed up bad. Someone had changed all my files and subdirs to 444 permissions. My system almost shutdown.
Most of the daemons that run are linked to /etc. Many configuration files are located here. I would say that /etc is the most important filesystem after the box is up and running.
Please let us know what your thinking is and what has spurred you to take up this quest for modifying file permissions.
I think you are chasing your tail, just a little bit.
Don't take this the wrong way. Only as a word of caution.

check-permissions
check-permissions(1M) System Administration Commands check-permissions(1M) NAME
check-permissions - check permissions on mail rerouting files SYNOPSIS
/usr/sbin/check-permissions [login] DESCRIPTION
The check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file that check-permis- sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is reported. Otherwise it reports that no unsafe directories were found. As to which .forward files are checked, it depends on the arguments included on the command line. If no argument is given, the current user's home directory is checked for the presence of a .forward file. If any arguments are given, they are assumed to be valid logins, and the home directory of each one is checked. If the special argument ALL is given, the passwd entry in the /etc/nsswitch.conf file is checked, and all password entries that can be obtained through the switch file are checked. In large domains, this can be time-consuming. OPERANDS
The following operands are supported: login Where login is a valid user name, checks the home directory for login. ALL Checks the home directory of all users. FILES
/etc/mail/sendmail.cf Defines environment for sendmail /etc/mail/aliases Ascii mail aliases file ATTRIBUTES
