[CLUE-Tech] Directory permissions -- problems with "-w--w--w-"

[Joe Linux]

The problem I'm having is Mandrake 8.2 is changing the permissions on my 
"/home/user" folder without me giving permission.  I set it to 770 and 
then shortly thereafter, the system changes it to 755.  This is not what 
I want, and I don't seem to be able to fix it.
