We need the ability to specify the location of the boot.log. Right now the boot.log location is specified via the org.jboss.boot.log.file java system property, but this is always set to $JBOSS_HOME/standalone/log/boot.log in the server start scripts. This should either not be set and simply default to $JBOSS_HOME/standalone/log/boot.log when unset so that it may be passed into the jvm, or, we need a JBOSS_BOOT_LOG env property that can override this value along the line of:

if [ "x$JBOSS_BOOT_LOG" = "x" ]; then
JBOSS_BOOT_LOG="$JBOSS_HOME/standalone/log/boot.log"
fi
while true; do
if [ "x$LAUNCH_JBOSS_IN_BACKGROUND" = "x" ]; then

1. Execute the JVM in the foreground
   eval \"$JAVA\" $JAVA_OPTS \
   \"-Dorg.jboss.boot.log.file=$JBOSS_BOOT_LOG\" \
   ...
