Update

As of October 2015, to apply apt-get update and apt-get upgrade, the packages are updated. Once the update of respberrypi-bootloader is done, the kernel is updated from 3.18.11 to 4.1.7 without making a backup copy of kernel.

Code> To execute rpi-update, the kernel is updated to 4.1.10. Unlike the update of raspberrypi-bootloader, rpi-update saves the contents of the /boot/ partition into the /boot.bak/ of rootfs, and the original kernel modules are stored into /lib/modules/ and /lib/modules.bak/.

Code>

As rpi-update is executed on 3.18.11 kernel, which is kept original setting as 2015-05-05-raspbian-wheezy is written into a microSD card, the directory under /lib/modules/ is changed as it is shown below.

Code>

In their name of directory, the “-v7” suffix indicates that its directory is for Raspberry Pi 2 (ARMv7 architecture).~


After the kernel is updated to 4.1.7 and rpi-update is executed, the directory under /lib/modules/ is changed as it is shown below.

Code>

If you need 3.x.x kernel or any other reason that you often bring back the original condition,
