c) Forgot to add that the cd command you state can't work is in fact not my instructions but those of the Archlinux patch developer. If you run the installation again (which I believe I said - if not should have) those directories will be recreated and the curl commands will bring down the patches.
I see you edited your reply while I had my reply window to you open so let me add, even thought I've already stated the obvious, yes you did not include reinstalling in the steps you laid forth which was the point of my first reply.
Might I suggest you clean up your set of directions to reflect proper steps so that maybe a new user would understand them. Certainly leaving out things like "Other commands exist in your home directory but you can omit them if you wish." which phrased the way you have makes no sense.
