Why do you want to destroy the possibility to automatically load the scripts? Did you read Documentation/gdb-kernel-debugging.txt in this regard? > diff --git a/scripts/gdb/vmlinux-gdb.py b/scripts/gdb/vmlinux-gdb.py > index ce82bf5..a9029f4 100644 > --- a/scripts/gdb/vmlinux-gdb.py > +++ b/scripts/gdb/vmlinux-gdb.py > @@ -13,7 +13,7 @@ > > import os > > -sys.path.insert(0, os.path.dirname(__file__) + "/scripts/gdb") > +sys.path.insert(0, os.path.dirname(os.path.realpath(__file__))) This works only so far as that (if you don't destroy the link) the main script will still find its modules. However, *.pyc files are then generated in the source tree, no longer in the output dirs. The code is designed to prevent this. You still don't explain to us why the existing code doesn't work for you and how you prefer to use it instead.
