> Let's do this:
> {code}
> if [ "x$JBOSS_JAVA_SIZING" = "x" ]; then
>    JBOSS_JAVA_SIZING="-Xms64m -Xmx512m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m"
> fi
> if [ "x$JAVA_OPTS" = "x" ]; then
>    JAVA_OPTS="$JBOSS_JAVA_SIZING -Djava.net.preferIPv4Stack=true"
>    JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true"
> else
>    echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS"
> fi
> {code}
> That will allow users to easily control memory sizing by setting that specific env var externally while still relying on our defaults for all the other fussy stuff in JAVA_OPTS.
> The JBOSS_JAVA_SIZING name was 20 secs of thought on my part.
