FreeBSD: speed test util

Just saw on youtube how to run the speed test in the terminal. Not sure if it is the same as http://www.speedtest.net/ but it looks very similar.

FreeBSD: Jails (4) - Thin jails using NullFS and template

As stated on chapter 14.5 of FreeBSD handbook (Updating Multiple Jails):

"The management of multiple jails can become problematic because every jail has to be rebuilt from scratch whenever it is upgraded. This can be time consuming and tedious if a lot of jails are created and manually updated.

This section demonstrates one method to resolve this issue by safely sharing as much as is possible between jails using read-only mount_nullfs(8) mounts, so that updating is simpler. (...) Additionally, it provides a simple way to add, remove, and upgrade jails."

So the idea now is to try this method of creating a template that can be reused to deploy as many jails as necessary and also make the update and/or upgrade of existing jails easier.
