[-- Attachment #1 --]
Hello,
I've beed working on the attached tool to find options/drivers that
depend on other options/drivers.
It currently removes one option at a time from LINT and tryes to build
the kernel sending the output to logs.
I have only tested this script on my one FreeBSD box and would like some
comments and suggestions to improve the script.
Andrew Turner
