14# @DESCRIPTION:
15# This eclass is used as a central eclass for accessing kernel
16# related information for source or binary already installed.

21# "kernel config" in this file means:
22# The .config of the currently installed sources is used as the first

20# KERNEL_DIR <string> The directory containing kernel the target kernel 29# @DESCRIPTION:

31# "/usr/src/linux"

22# CONFIG_CHECK <string> a list of .config options to check for before 35# A string containing a list of .config options to check for before

48# In general, most checks should be non-fatal. The only time fatal checks should
49# be used is for building kernel modules or cases that a compile will fail
50# without the option.
51#
52# This is to allow usage of binary kernels, and minimal systems without kernel
53# sources.
