$ unik daemon —debug=true --logfile=ukd.log
ERRO[0000] running daemon failed: [cmd/daemon.go:57] failed to open log file ukd.log for writing: {open ukd.log: no such file or directory}

Running touch ukd.log and re-running the above works. Seems like it would be more friendly if unik simply created the file if needed.

If this behavior is desired, fixing it might make a good entry-level project, so I can take a stab at it and submit a PR as time allows.
