Common Lisp Scripting with Roswell

"Roswell Script" is implementation-independent Common Lisp scripting program which uses Roswell. Although Roswell itself is a unified interface to Common Lisp implementations, it also encourages writing scripts with it.

To start writing it, run ros init in your terminal:

$ ros init
Usage: ros init [template] name [options...]

We constantly have around 1000 running zones and around 1000 stopped zones on a SmartOS machine. Having a lot of zones on the machine cause zone operations to take around 5 - 15 Minutes apeice. That it a huge amount of time. For example a few months ago we had a machine reboot and it took about 4 hours for all of the zones to transition to running.

4 hours. That sucked.

Before that we had been digging into speeding things up, but 4 hours made it a major priority.

These files are a short description of what we found and did to speed things up.
