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...
