So, to get something like /etc/rc.local you can use the custom SMF import facility. (See the source for more information about how this actually works.)

/opt is mounted out of zones/opt by default. You can create a directory /opt/custom/smf and populate it with SMF manifests. Any manifests you put in there will be imported by SmartOS when it boots. Below is an example SMF manifest that simply starts /opt/custom/bin/postboot, a self-explanatory shell script that you can use like /etc/rc.local.

Note that it would likely be better to customise and respin your own images, as putting a bunch of platform state in the zones pool undoes some of the benefits of the ramdisk platform architecture that SmartOS has.

Node Error Handling and Domains

"Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature." - Albert Einstein

"Master of my domain" - Larry David

Error handling in an asynchronous language works in a unique way and presents many challenges, some unexpected. This tutorial reviews the various error handling patterns available in node, and explains how domains can be used to improve it.

There are four main error handling patterns in node:

Error return value

log all incoming http requests

app.http.before.push(function(req, res){
  app.log.info(req.url);
  res.emit('next');
})

	var a = [];

	a[Math.pow(2, 32) - 2] = "max index"; // highest non-expando indexed property
	console.log(a.length === Math.pow(2, 32) - 1); // true

	try {
	a.push("whoa", "EVEN MOAR WHOA");
	} catch (e) {
	console.log(e instanceof RangeError); // true
	}
