kernel && patches

[nestu]

Hi everyone! ;)
I wanted to ask if there is any policy about grabbing kernel source, if 
full source _must_ be DLed everytime.  I'm asking, 'cause when I bump up 
the kernel's version, I thought about patching it: maybe we could check 
for a base install  -say, for example, linux-XXX- and if it is there, 
get the patch to bump it up to  linux-XXX-yyy. Furthermore, IAC, the 
user can be prompted if he/she wants to fetch full source, or viceversa 
( default is fetch the full source, but if a patch can be applied, 
prompt the user for what should be done).
Another thing I thought of is kernel's config placement. How about 
putting a default location, and checking there first for it, and if it 
not there, prompt the user. Maybe this could be applied to more modules 
where a default_config could be saved in ${CONFIG_DIR} or something 
alike? Am I outdated on this? Pro/cons? What 'ya think ?
C U,
nestu ;)))
