What about NixWRT?
|
||
|
|
|
||
|
|
This is an in-progress rewrite of NixWRT, incorporating Lessons
|
||
|
|
Learned. That said, as of today it is not yet at feature parity.
|
||
|
|
|
||
|
|
Liminix will eventually provide these differentiators over NixWRT:
|
||
|
|
|
||
|
|
* a writable filesystem so that software updates or reconfiguration
|
||
|
|
(e.g. changing passwords) don't require taking the device offline to
|
||
|
|
reflash it.
|
||
|
|
|
||
|
|
* more flexible service management with dependencies, to allow
|
||
|
|
configurations such as "route through PPPoE if it is healthy, with
|
||
|
|
fallback to LTE"
|
||
|
|
|
||
|
|
* a spec for valid configuration options (a la NixOS module options)
|
||
|
|
to that we can detect errors at evaluation time instead of producing
|
||
|
|
a bad image.
|
||
|
|
|
||
|
|
* a network-based mechanism for secrets management so that changes can
|
||
|
|
be pushed from a central location to several Liminix devices at once
|
||
|
|
|
||
|
|
* send device metrics and logs to a monitoring/alerting/o11y
|
||
|
|
infrastructure
|
||
|
|
|
||
|
|
Today though, it does approximately none of these things and certainly
|
||
|
|
not on real hardware.

points and routers we reviewed, not a single one took full

advantage of the basic application armoring features provided by
