I think I was alluding that another option (not saying that it's the
best but IIUC your requirements it'd be the best fit)):
5) Add a keepalive configfs knob, if set to a non-zero value netconsole
will send an empty (?) message at given interval
Pros:
- truly does not require a user binary to run periodically, netcons
would set a timer in the kernel
Cons:
- does not provide the arbitrary "console bypass" message
functionality
