Setup environment variables

To make the documentation a bit more "generic" we start by setting some environment variables.

vi /etc/lbu/lbu.conf

Make sure that the variable LBU_MEDIA is not commented (by removing the leading '#').

You also need to set a appropriate value for your LBU_MEDIA. The media you choose will be the media where you store your settings/configuration.

Note: Even if you have you alpine installed on CF, HD or USB you can still choose to save your config on some other media that suits your needs. But remember that both the media where you have your Alpine system AND the media where you have your config need to be in your box when booting it.

Examples:

LBU_MEDIA=usb

or:

LBU_MEDIA=sda1

Now that you have your /etc/lbu/lbu.conf configured for your needs, we will set the environment variables (note the leading .).

. /etc/lbu/lbu.conf

You can test if your environment variable was set:

echo $LBU_MEDIA

It should output something like usb, sda1, or whatever you just configured.

Back up your config

Before starting to upgrade, it's wise to save your configuration.
