Just installed MDK 10.0 RC1 w/2.6.2. Got Jackd to fire up but in non
root mode, although jackd seems to be running, Ardour (beta 11.2)
complains that it cannot connect to Jack client. I set up tmpfs...is
this needed on 2.6? Also, I run Jack once from Qjackctl. If I stop it, I
cant run it again. Should the temp files placed in /tmp be deleted after
jack quits? I was almost sure this was what was happening on MDK 9.2.
