kget Get list of kernel configuration.
 
This utility allows to gather device configuration which possibly
was changed in userconfig (-c) session, and to save it to /kernel.config
file on startup floppy, so that when user boots next time, the
settings will automatically be changed.
 
Usage is straightforward:
 
kget [-incore|kernel_name] [vanilla]
 
E.g.: Get device configuration of running kernel
 
kget -incore
 
Produce list of parameters changed from /stand/vanilla
 
kget -incore /stand/vanilla
 
(You can redirect the stdout to /kernel.config - this list
already contains all the requires keywords.)
