Usage: cl-kernel [options] [-c FILE|-o]
|
|
|
|
Make kernel.
|
|
|
|
Options:
|
|
-c, --kernel-config FILE Kernel configuration file to use for compilation
|
|
--dmraid Include RMRAID support
|
|
-e, --extraversion VER Specify extraversion for kernel
|
|
-h, --help Print this help message
|
|
-k, --kerneldir DIR Location of the kernel sources
|
|
--lvm Include LVM support
|
|
--mdadm Copy /etc/mdadm.conf to initramfs
|
|
-m, --menuconfig Run menuconfig after oldconfig
|
|
--no-clean Do not run make clean before compilation
|
|
-o, --use-own-config Use config from kernel directory.
|
|
-q, --quiet Do not display kernel compilation process
|
|
|
|
Examples:
|
|
|
|
The most common use is to run it like this, which build and install current kernel.
|
|
|
|
$ cl-kernel
|
|
|
|
$ cl-kernel --menuconfig --kerneldir /usr/src/linux-2.6.31-gentoo-r6
