Turris Omnia
************
This is a 32 bit ARMv7 MVEBU device, which is usually shipped with
TurrisOS, an OpenWrt-based system. Rather than reformatting the
builtin storage, we install Liminix on to the existing btrfs
filesystem so that the vendor snapshot/recovery system continues
to work (and provides you an easy rollback if you decide you don't
like Liminix after all).
The install process is designed so that you should not need to open
the device and add a serial console (although it may be handy
for visibility and in case anything goes wrong). In outline
1. build a "recovery" system with useful btrfs tools
2. boot that system using TFTP or a USB stick
3. once booted, mount the real root filesystem on /mnt
4. take a snapshot using schnapps, and then delete everything
5. use min-copy-closure -d /mnt/@ to copy the real configuration
to the device
6. reboot into a fully operational system
Detailed instructions to follow...
