Configuration of much of Linux is fairly straightforward nowadays but seems worth documenting since (for me at least) it is not implicit. While many other devices and their operating systems are likely to be pre-configured or designed for automatic configuration my use of Linux tends towards some level of explicit configuration. Ultimately this is something that I embrace as it builds understanding and aids in any troubleshooting where any issues can be very intentionally worked through rather than stumbling around somewhat blindly due to incompatible magic.
