Bsd update and kernel source updating
Jails are isolated virtual instances of Free BSD that all run off the same kernel.There's no performance hit at all, even with the network stack and disk I/O.This article isn't a comprehensive tutorial that covers every possible situation; rather, it covers the most common situation: updating your source with CVS, building that source code, and installing it on the build machine.While you could have your own source code repository, or tunnel the whole process through , most users just use this method.Designed to be easy to use, yet powerful and flexible, allows you to track bank accounts, stocks, income and expenses.As quick and intuitive to use as a checkbook register, it is based on professional accounting principles to ensure balanced books and accurate reports.The Net BSD Project provides comprehensive documentation on how to upgrade the operating system.
Virtual machines mostly solve this isolation issue, but they have some drawbacks. There are speed penalties when running things in a VM.Part of this requires you to choose a release engineering tag. It is the word RELENG followed by an underscore and the version number.For example, if your system is running Free BSD 8.1-RELEASE then your release engineering tag is RELENG_8_1. This is my preferred version so I will use this in my examples.Most of what I touched on in those articles hasn't changed much--the installer is prettier, hardware support is updated, but Net BSD is still a basic, reliable BSD-based system.Cross-building releases on something as old as that Multia isn't such a grand idea, however, so I started over on a modern Athlon system.
Why dedicate an entire machine to one specific service when you can make a virtual machine?
