It would probably be clearer to untangle these in one go, leaving the
result looking like:

XENCONSOLED_PIDFILE="@XEN_RUN_DIR@/xenconsoled.pid"
#XENCONSOLED_TRACE="none|guest|hv|all"

XENSTORED_PIDFILE="@XEN_RUN_DIR@/xenstored.pid"
#XENSTORED_TRACE="@XEN_LOG_DIR@/xen/xenstore-trace.log"

I'd also be tempted to fold this and the NetBSD change together.  It's
not as if these bugfixes are distro-specific.


It looks like a bug in NetBSD in c/s 2e8644e1d90, which was copied into
FreeBSD by c/s 5dcdb2bf569.  (P.S. Sorry Roger - both your bugs,
starting from a decade ago).  It really is idiotic that we've got a
commonly named *_TRACE variable with totally different semantics for the
two daemons.  Then again, its far too late to fix this :(
