I have the same on AIX (slightly different commands) and that is just how it works. The safest way to change such files is by editing the ACL. What you are saying with your chmod is "Overwrite the security permissions with RWX --- ---" so that's what it does. Everything else is invalidated.

perhaps you may have more success with the other format of chmod where you specifically grant/revoke accesses:-

Code:

chmod u+r file
chmod u+w file
chmod u+x file
chmod g-r file
chmod g-w file
chmod g-x file
chmod o-r file
chmod o-w file
chmod o-x file

I've never tried this, and you may be able to combine them, but the basically system is doing what you ask it to.




I hope that this helps
