Wandboard - separate boot partition

[opotonil]

How can I separate the boot partition? I want use BTRFS for the rootfs partition.

The current in kernel BTRFS support is enough? Or I will require to use a initramfs.

btrfs is currently not in the main kernel, and so loaded as a module. This means yes it would need to be in an initramfs.

Guess if you go that direction, either work out how to run mkinitcpio for arm arch on another architecture (e.g.on a desktop computer), or booting the wanderboard from an external file system (e.g. USB - alas I don't know the wanderboard hardware), and then creating an initramfs wih the right modules.

The actual creation of the boot partition is quite simple.

Anyway what I did on my NSA325, was to keep a root fs in ext4, and just make the user partition in btfs. Root I keep small, 2GB IIRC, the home directory is then 1TB, and used for doing backups on. btrfs is good for thinks like snapshots - so ideal for backups.
