1) Determine the current version of the Linux kernel incorporated into our distribution. Check the available updates automatically, whether in Debian (apt ) or in Fedora/Red Hat (via yum).
2) Carry out an automatic update of our distribution. Check possible dependencies with other modules used (whether pcmcia or others) and with the bootloader (lilo or grub) used. A backup of important system data (account users and modified configuration files) is recommended if we do not have another sytem that is available for tests.
3) For our branch of the kernel, to determine the latest available version (consult http://www.kernel.org) and carry out a manual installation following the steps described in the unit. The final installation can be left optional, or else make an entry in the bootloader for testing the new kernel.
4) In the case of the Debian distribution, in addition to the manual steps, we saw how there is a special way (recommended) of installing the kernel from its sources using the kernel-package.
