jackd2 in debian/ubuntu ships with both jackd and jackdbus. Many jack 
applications that find no jack server running will start one using jackd 
with the temporary flag (we hope). There have been at least some versions 
of jackd where this was broken and the started jack server would continue 
running. This would block jackdbus from starting. This bug has been fixed 
now for over two years. However, ubuntu shipped the buggy version in their 
LTS (14.04) and there may be applications that do not bother to set the 
temporary flag. Running jackdbus at session start is best practice to 
solve this problem. Or use some other method of getting desktop audio into 
jack without pulseaudio. On my older system I just did a chmod -x jackd to 
solve that... I don't need to any more.
