PATCH 1/1 update faq

One cleanup reqarding ketchup usage & one additional feature (make O=) for the FAQ.

faq.dev renamed from faq +12 -1

 that is should break hardlinks; vim can be taught by setting
 "set backupcopy=auto,breakhardlink" in your ~/.vimrc .
 Example usage:
-  ketchup 2.6.12
+  ketchup 2.6 (currently 2.6.12)
   cp -al linux-2.6.12 mytree
   # change some random files in mytree/
   diff -pruNX Documentation/dontdiff linux-2.6.12 mytree > my_new_patch
 
+Another useful feature is the kbuild O= feature. This allows you to save
+output files in a separate directory. Thus, one could, in parallel to
+the linked source trees, create separate build trees, e.g. linux/views/
+and linux/build/. Example usage, presuming you followed the ketchup
+steps above in a directory called views:
+
+  cd ../build/
+  mkdir linux-2.6.12
+  cp backup_config_from_somewhere_else linux-2.6.12/.
+  cd ../views/linux-2.6.12/
+  make O=$(pwd | sed s/views/build/) -j4 oldconfig bzImage
 
 Since typing Signed-off-by gets boring, here's a ~/.vimrc sample:
  map <F1> ^iSigned-off-by: Random C Developer <[email protected]><CR><ESC>^
