Changing fname in /proc filesystem
I wrote a wrapper (call it prog1) around another program (call it prog2) for security purposes. When prog1 launches prog2 it sets the argv[0] value to be "prog1" so that "prog2" does not show up when you use the "ps" command. Howerver, if you use the option "-o fname" with "ps" then the file name for prog2 still shows up (also when running "sdtprocess", this being Solaris). I'd like to stop this from happening, but the file name is apparently being pulled from the /proc file system and I don't think prog1 is going to have permission to change any values in prog2's state. So I have 2 questions:

1) Is it even possible to change the filename values in prog2's /proc entries through any method?

2) Is there any way to do this from within prog1? (I don't have access to prog2's source code or I wouldn't have needed a wrapper to begin with)

Thanks or any help.
