Minor fixes

Minor set of tweaks here to fix up an installed bt-daemon to work correctly.
Also a style-based change in configurator.

Whilst we're all looking at this, could someone briefly check my array-dez branch, https://github.com/ikeydoherty/buxton/commit/2468d56ac29fdcffab1de95b98d5dc80ac7a9afa ?

That side *seems* to work right now, but I need to actually ammend it a few times and get the make check building again :)

CC: @mikeleib as c0aaf72 affects his configurator.
