I've run across a strange issue. Using logread -e "d.*mon" returns nothing, but passing it through grep with logread | grep "daemon" works. Is this a bug or does the -e switch only understand regex like (\w*[A-Z]) ? To that end, not even "d.*mon" works. I should think d.*fo returns lines with daemon.info, but instead, I find only one about my SSH authentication with dropbear.
I've looked on the LEDE issue tracker, and the GitHub page for the OpenWRT package (linked on the tracker) for anything related to logread, so either I have run across a bug, or I am not using this quite right -- I apologise if the latter is the case.

Sorry, I gave the wrong link of the code. Should not just randomly search in github. Below is the true link of ubox and -e is supported.
