FreeBSD 8.1 uses different open source philosophy
FreeBSD may not receive the attention that Linux does, but its latest upgrade could provide some instruction to the makers of Ubuntu about how to do open source releases. The makers of Ubuntu and the popular Linux Mint usually add new features to every release of these Linux distributions, whether or not these are features that the average users will ever need.
FreeBSD 8.0 was the last large release of the operating system. Like Linux, FreeBSD is known for its security and stability, but it has never captured the imagination of computer users in the same way that Linus Torvald’s operating system has. Instead of introducing new features, 8.1 featured on making certain features released with the 8.0 upgrade more stable and improving the features that the user requested.
