From the PR:
When submitting PR 183682 I was unaware the patch as in PR 182792 wasn't
committed yet. So to my amazing I just noticed the startup problem still
Enclosed patch is basicly the same as the uncommited one, but besides the
removal of the -w option, knotd now starts by default as a daemon (-d) in
stead of interactive (-i). So I could simplify the startup script a lot.
