The wakatiwai.sh script can be used to quickly generate disk images containing the Wakatiwai Bootloader. Its usage is as follows:
usage: wakatiwai.sh [-hl] <profile>
-h --help : Prints this message
-l --list : Lists profiles
In order to facilitate this, .json files in the tests directory exist which describe how a disk image should be formatted and populated, as well as providing a config file for Wakatiwai itself. The profile itself is a simple JSON object containing two fields; config, which contains a config object as would be found in a wtconfig.json file, and an array called partitions, itself containing objects with the following fields:
| Property | Example | Notes |
|---|---|---|
type |
20, F90358A9-1AA5-4264-8C74-C298A4B801B1, BOOT |
This is either a GPT Partition Type identifier as used by fdisk or a a type GUID for this partition. See fdisk_gpt_table.md for a complete list.N.B. This field may also be "BOOT". If so, all other fields bar size will be ignored, and this partition will be automatically configured with the Wakatiwai bootloader. |
size |
64M, 300M, 8G |
The size of the partition in either Megabytes (M) or Gigabytes (G = 1024M). |
fs |
ext2, fat32, swap |
The filesystem to be used by the partition. Click here for a list of currently supported filesystems. |
- ext2/3/4
- fat12/16/32
- swap
- btrfs
To run an disk image in QEMU, simply run ./run.sh <disk-image>.img.
