This may be a SuSE-ism.  There is a collection of /etc/permissions... 
files, including a directory into which packages can drop fragments.  Each 
line of each file gives a filename, an owner:group, and a mode (e.g. 4755).  
After you install a package using the GUI (YaST2), the package manager does 
various postprocessing including interpreting these files and changing 
owners and modes.  /etc/permissions.local is for local tweaks, overriding 
general and package drop-in permissions files.

Right: if you just set 4755 then it will revert at the next security patch.  
That's why SuSE has provided this persistent configuration file.

I guess if the permissions script doesn't have an equivalent in other 
popular distros, customizing the mode is not so attractive.
