Alright, try the following. 'cd' to the directory your source is in. Then try the following command while you're in the source directory:
Code:
p1 < /usr/local/src/quota-2.6.1-1-jquota.diff
If that doesn't work, try substituting 'p1' with 'p2', 'p0', etc, etc.
I had some trouble trying to figure out how to apply my first patch too. If all else fails, post here again. Also, try not posting the same thread over. It just complicates things a bit. But you probably already know this.
