Script to install/update kernel packages

[djemos]

New users usually have difficulty to upgrade the kernel or install generic kernel.
If they forgot to run update-grub before reboot then will end with a non bootable system.
In this case an experienced user can fix the problem but new users cannot.

In Slackware upgrading a new kernel package, the previous installed kernel version is also removed from the system.
This script can upgrade as usual the kernel with the new one existed on repos and also run update-grub in the end.
Also can install the new kernel keeping also the previous kernel or kernels installed.
If user want to install or upgrade the generic kernel then an initrd.gz is created so system can boot.
In all cases update-grub is always run in the end so system always be bootable.

Of course user can always remove old kernel packages at any time by hand and run update-grub.

Running the script with no parameters or -h parameter will get the following output.
