Onboarding ā Dakota ISO#
Prerequisites#
| Tool | Notes |
|---|---|
podman | Rootless. sudo-prefixed builds will fail with "please use unshare with rootless" |
xorriso | brew: brew install xorriso Ā· distro package also works |
mtools | brew: brew install mtools Ā· needed for FAT ESP construction |
mksquashfs | brew: brew install squashfs |
| Free disk (~25 GB) | Must be on /var ā never /tmp (tmpfs ~16 GB, too small) |
| QEMU (optional) | brew: brew install qemu ā needed for boot testing |
Clone and first build#
git clone https://github.com/projectbluefin/dakota-iso

sudo chown $USER:$USER /mnt
just workdir=/mnt iso-sd-boot dakota
Branch target#
