we have forwarding but no dns, maybe because we haven't told
dnsmasq about any upstream servers

to add firmware we need to put files in /lib/firmware, which means
a module
i guess we should do that in the device module
we can create the firmware files as packages
for the cal data we would like to get it from the device MTD "art"
partition at
boot time.

Found and fixed a bunchg of things that were stopping ath10k from
working. The remaining problem is (I think) that insmod is not
synchronous, so "ip link set up dev wlan1" doesn't work immediately
after the module is inserted. Maybe we need another netlink thing
to wait until the interface is present.

ath10k works, but the wlan module loading stuff is quite kludgey
I wonder if wlan0, wlan1, eth0, eth1 etc should be defined per-device
- how does the aplication config know which devices exist? If we
decide to switch to some form of persistent device naming, the names
will differ from one device to the next. Perhaps the device should
also provide standard names where possible?
services.network.links = {
lan = interface { ... };
wan = interface { ... };
wlan_24 = interface { ... };
wlan_5 = interface { ... };
}

We have a flashable image!
Now we can use the gl-ar750 for internet access in the shed, we can
apppropriate the other device that's in there and try Liminix on it
Fri Mar 3 23:08:58 GMT 2023
If we're going to unplug serial console from the gl-ar750 maybe we
should install an ssh server first.
0) set a root password
1) allow setting a root password from configuration.nix
(means defining config.users properly)
2) allow authorizedKeys per user
3) dropbear service
4) see if the wired lan works! :-)

To improve logging, each service should have its own s6-log service
which prefixes the service name onto the log line and then sends to
stdout
https://skarnet.org/software/s6/servicedir.html
https://skarnet.org/software/s6/s6-log.html
As far as I can tell, the `log` directory inside the service
directory should itself be a service directory for the s6-log
process that does this
.... hahaha no that doesn't work
s6-rc, for some reason, ignores the `log` directory and requires
that loggers be done with consumer-for and producer-for instead

notes for this week's news update
* ath10k kernel support and and firmware
- 5GHz wifi works
- need to retrieve the firmware from a special - partition on the
device itself, so we do that using a service that - the wlan
interface depends on
* replace waitup with more generally useful ifwait
to make the ath10k load at boot, we need to insert the module and then
wait for it to do something or other in the background before we can
configure the interface. so we need something like waitup but
for presence not operational state
it turns out that a program that just waits for a particular interface
state and then exits is quite simple to add into run scripts and
we don't need all that notification-fd stuff anyway
* move FW_LOADER* config to modules/base
* rejig config a bit.
- device hardware characteristics are now under
the `hardware` key and include the available network interfaces.
- options for users and groups are now defined a bit more
specifically than "attrset", making it possible to e.g. set a
root password
- dts is moved from `boot` to `hardware`
* now producing flashable images, so you can generate a liminix config
and write it to the device instead of having to boot using TFTP and
a serial console every time
* ssh support
* prefix logs with the service name

Added swconfig: it was a straight copy from nixwrt and hasn't changed
upstream since. But don't need it, because the lan port works fine
without it (I assume both lan ports and the cpu are all connected
untagged)

- nftables needs

- jansson? what is that?

Check in morning, but whichever port the ethernet cable is plugged into,

figure out how to add these to gl-mt300a device config
then extedner.nix can add a bridge
