byteos.yaml

byteos.yaml is a configuration file for the ByteOS.

You can change the config in this file. For example, you want to use the ext4 fielsystem.

Set the root_fs to 'ext4' or 'ext4_rs' will change the root_fs from 'fat32' to 'ext4'.

The 'ext4' and 'ext4_rs' are the different implementation of the ext4.

TIPS: Make ensure that the mkefs version of your system lower than 1.70. If not, you have to use another argument to build the ext4 image.
