I don't like introducing uci capabilities to the low-level logd daemon. 
Intuitively it seems better to keep logd simple and separate from the file 
system.

The old approach of initscript and -S option might be adapted to the possible 
resizing need. The resize argument might be passed similarly from a command 
line option or as a parameter to an ubus call.

I think that the current default of 16 kB log buffer in RAM is too small for 
modern routers, especially if you have packages that produce some output to 
the bootlog. E.g. in my own router the default 16 kB is not enough to capture 
the whole boot process, so I have patched the logd initscript in my own build 
to default to a 64 kB buffer. Maybe the global default log buffer size could 
be increased?
