what's best way for playing with kernel configurations and source code

[Alshamlan, Mohammad]

Hi everybody,

How you can reconfigure and also modify your source code without
affected your system? Please, if you want to suggest a virtual machine is
the best option, then could you tell me why? Thanks in advance.

Usually while kernel development, you do not overwrite your existing
distro-provided kernel, but install your built kernel as a new option.
This helps you in not losing access to your machine in case the kernel
changes you have made are serious.

For keeping different configurations at a source level, you can use
git local branches. See

If they're serious enough you might still break your file system and
lose your data, so it's in any case good to have a backup. ;-)
