# More of a tutorial here:
extended_usage() {
cat <<-EOT
This script is useful in situations where you require an initrd image
to boot your computer.
For instance, when booting a kernel that does not have support for your
storage or root filesystem built in (such as the Slackware 'generic'
kernels').
* When you run the script without parameters, it will examine your
running system, your current kernel version and will output an example
of a 'mkinitrd' commandline that you can use to generate an initrd
image containing enough driver support to boot the computer.
* You can make it more specific: when you add the filename of a kernel
as parameter to the script, it will determine the kernel version from
that kernel, and also give an example of the lines that you should add
to your '/etc/lilo.conf' file.
* If you want your initrd image to have a custom name instead of the
default '/boot/initrd.gz' you can add it as another parameter to the
script, as follows:
$(basename $0) -a "-o /boot/custom.gz"
The arguments to the '-a' parameter will be used as additional arguments
to the 'mkinitrd' command.
* If you need additional modules in the initrd image, apart from what
the script determines, you can pass then to the script using the '-m'
parameter as follows:
$(basename $0) -m "uhci-hcd:usbhid:hid_generic"
The above example adds support for USB keyboards to the initrd - you
may need that if you have encrypted your root partition and need to
enter a passphrase using a USB keyboard.
* Instead of copying and pasting the script's output, you can create
an initrd by directly executing the output, like in this example:
EOT
echo " \$($(basename $0) --run /boot/vmlinuz-generic-smp-2.6.35.11-smp)"
cat <<-EOT
That used the '-r' or '--run' switch to make the script only write
the 'mkinitrd' commandline to the terminal.
* When you want to add a section for a specific kernel to
'/etc/lilo.conf' directly, use the '-l' or '--lilo' switch and use a
command like in this example:
EOT
echo " $(basename $0) --lilo /boot/vmlinuz-generic-smp-2.6.35.11-smp >>/etc/lilo.conf"
cat <<-EOT
That command will result in the following lines being added to your
'/etc/lilo.conf' file (example for my hardware):
# Linux bootable partition config begins
# initrd created with 'mkinitrd -c -k 2.6.35.11-smp -m ata_generic:pata_amd:mbcache:jbd:ext3 -f ext3 -r /dev/hda7'
image = /boot/vmlinuz-generic-smp-2.6.35.11-smp
initrd = /boot/initrd.gz
root = /dev/hda7
label = 2.6.35.11-smp
read-only
# Linux bootable partition config ends
The last two examples show how easy it is to configure your computer
for the use of an initrd if you need one. The only thing left to do
afterwards is running 'lilo'.
