* the reason we can't reboot is that there is a service to add each
lan device to the bridge which does ifwait $dev running, which doesn't
return until there's something plugged in. So s6-rc hangs indefinitely
until the lan switch is fully populated. This is definitely a
"next milestone" thing
until the lan switch is fully populated. This is definitely a "next

* another example of "thing that depends on other thing but which it
is actually OK if neither of them happen" might be "mount a
filesystem if there is a usb mass storage device attached"
* I don't know if failover also fits into the model we don't quite
have. LTE route depends on pppoe not being healthy
we can have services (or bundles) that aren't part of the default target,
and plumb them into events of some kind (netlink?) to bring them up/down?
we can use s6-rc instanced services:
https://skarnet.org/software/s6/instances.html
"s6-instance-create and s6-instance-delete are relatively expensive operations, because they have to recursively copy or delete directories and use the synchronization mechanism with the instance supervisor, compared to s6-instance-control which only has to send commands to already existing supervisors. If you are going to turn instances on and off on a regular basis, it is more efficient to keep the instance existing and control it with s6-instance-control than it is to repeatedly create and delete it. "
Probably we need something that reads netlink messages and converts
them to a format that we can use to control services. Is there a
benefit to using services here and not just running commands? it means
the system state change we desire will stay changed.
TODO items not to lose track of
- speed testing (iperf)
- make gl-ar750 tftpboot build again
- finish belkin
- install sniproxy
- is there something simple we can do to make it reboot again?
