Log verbosity ignored if running in background

[CuriousMike56]

The default configuration in the Linux server package contains:

foreground = n
verbosity = 1
logverbosity = 1 

With foreground disabled, the terminal output ends when it's forked into background as expected:

However, with logverbosity = 1 the server.log file should contain the full output. Instead it mirrors the terminal output:

Verbosity settings work as expected if you enable foreground mode:

foreground = y
verbosity = 5
logverbosity = 0
