|
||||
|
||||
Our test for liminix-rebuild uses qemu block device and ext4 instead
|
||||
of phram because -device loader doesn't seem to survive a reboot.
|
||||
And it needs some free space in the ext4 partition inside the
|
||||
mbr image so that it can install new stuff. However, the
|
||||
filesystem is sized to be near-full.
|
||||
|
||||
If the mbrimage output is to be much use, probably there should be
|
||||
some way of telling it how big the disk is. Maybe it should use
|
||||
hardware.flash.size?
|
||||
|
||||
UBI also does a bad job of integrating into the hardware.flash hierarchy
|
||||
(but ubi is also more complicated as the ubi volumes are "nested" inside
|
||||
an MTD partition)
|
||||
|
||||
To move forwards with this test I think I will make it not depend on
|
||||
mbrimage for now, but we have to come back to this. Maybe importing
|
||||
the mbrimage module provides new hardware.disk = { partitions, size etc}
|
||||
config options.

https://developer.ridgerun.com/wiki/index.php/Setting_up_fw_printenv_to_modify_u-boot_environment_variables#Preparing_the_fw_env.config_file
|
||||
|
||||
can we extract the fw_env config data somehow to produce an appropriate
|
||||
file for the device?
|
||||
|
||||
the device config needs to specify partition name and offset at minimum,
|
||||
possibly also size.
|
||||
|
||||
we can create a service that writes the config based on those values. but
|
||||
if we are to be using fw_setenv from the shell, there is no service
|
||||
which depends on that service. whatever defines the service also needs
|
||||
to add it to system.services so that the recovery system can specify it

|

How do we min-copy-closure to the device when we don't have anything
|
||||
hooked to the LAN port? It's rather easy to break the WAN connection
|
||||
when it involves going out to the internet and back
|
||||
|
||||
* Don't want to plug it into the actual lan because it's doing dhcp service
|
||||
and that is going to confuse
|
||||
|
||||
* the machine we're copying from is loaclhost
|
||||
|
||||
* we could do some kind of port forwarding thing? maybe a port forward on
|
||||
run-border-vm qemu user networking ...
|
||||
|
||||
* static route on loaclhost?
|
||||
|
||||
512 sudo ip netns add test-lan
|
||||
514 sudo ip link set dev enp1s0 netns test-lan
|
||||
|
||||
525 sudo ip link add veth-test-lan type veth peer veth1 netns test-lan
|
||||
533 sudo ip netns exec test-lan ip link add name br0 type bridge
|
||||
536 sudo ip netns exec test-lan ip link set veth1 master br0
|
||||
537 sudo ip netns exec test-lan ip link set enp1s0 master br0
|
||||
sudo ip netns exec test-lan /nix/store/dh66q9k402pwpmmgc983xwmwb3vvvjbr-busybox-1.36.1/bin/busybox udhcpc -i br0
|
||||
|
||||
then we could add a route to 10.8.0.1/32 with dev veth-test-lan ?

|
||||
|
||||
This is all beside the point right now because the _recovery_ system
|
||||
does not run all this stuff - it just has a dhcp client on the lan
|
||||
interface. We could plug it straight into the switch.
|
||||

||||
|
||||
COPYING /nix/store/dlz86nip271ybaz0cip7bgkbzijk0cr7-make-stuff-mips-unknown-linux-musl TO //persist
|
||||
As we already just plugged it into enp1s0 on loaclhost, could we
|
||||
do somethin to put it on the lan from there? add it to vbridge0?

OK, so

# on device

mount /dev/mmcblk0p1 /mnt
|

[ take a snapshot if needed ]
|
||||
[ clear out the turrisos files ]
|
||||
ls /mnt/@
|
||||
|
||||
# on build
|
||||
|
||||
$ nix-build -I liminix-config=./examples/rotuer.nix --arg device "import ./devices/turris-omnia" -A outputs.systemConfiguration
|
||||
$ nix-shell --run "min-copy-closure -r /mnt/@ root@recovery.lan result "
|
||||
|
||||
# on device
|
||||
|
||||
$ mkdir /mnt/@/persist

$ /mnt/@/nix/store/swf3vn9bzx198c0cwp6naq0glqa9192n-make-stuff-armv7l-unknown-linux-musleabihf/bin/install /mnt/@/
|
||||
|
||||
this fails because it tries to copy from the unprefixed nix
|
||||
store. Also probably it should mkdir $prefix/persist. Also it needs to
|
||||
create $prefix/boot: it's too late to do that with `activate`
|
||||
because u-boot will need it to exist in order to load the initramfs
|
||||
that runs activate
