>Description:
"options INCLUDE_CONFIG_FILE" allows the inclusion of the kernel
configuration file into the kernel image. config.8 suggests the
command
strings kernel | grep ___
to recover the original configuration file. Instead I propose this
command
strings kernel | sed -n 's/^___//p'
which is less likely to match false positives and removes the
protecting leading underscores.
