修改 linux kernel 与 kernel module 的安装路径

指定 bzImage 的安装路径

设定 INSTALL_PATH 即可，示例如下：

longyu@longyu-pc:~/linux-4.19.67$ mkdir /tmp/kernel
longyu@longyu-pc:~/linux-4.19.67$ export INSTALL_PATH=/tmp/kernel
longyu@longyu-pc:~/linux-4.19.67$ make install
sh ./arch/x86/boot/install.sh 4.19.67 arch/x86/boot/bzImage \
        System.map "/tmp/kernel"

查看指定目录的内容：

longyu@longyu-pc:~/linux-4.19.67$ ls /tmp/kernel
config-4.19.67  System.map-4.19.67  vmlinuz-4.19.67

指定 kernel module 的安装路径

设定 INSTALL_MOD_PATH 变量即可，示例如下：

longyu@longyu-pc:~/linux-4.19.67$ mkdir /tmp/kernel-lib
longyu@longyu-pc:~/linux-4.19.67$ export INSTALL_MOD_PATH=/tmp/kernel-lib/
longyu@longyu-pc:~/linux-4.19.67$ make modules_install
