I have a question about preserving my current Linux installation. Let's say I take my fully updated system offline, meaning everything installed on it stays as is, and I want to ensure that in the future, I can do a fresh install on the same hardware. My goal is to have all my applications, dependencies, the Linux kernel, drivers—basically everything—at their current versions. I'm looking for a method to create an offline snapshot, not just of the files and structure, but a way to reinstall everything without needing internet access later on. I want to know if there's a way to get all my programs (including those running through WINE) nicely packaged for future use. Does that make sense?

Have you considered using an immutable distro? They allow you to have a setup that is hard to change, ensuring your configurations remain consistent. This could be a straightforward way to maintain your environment.
You can achieve this by following a few steps. First, set up your /home directory on a separate partition or disk. Then, make sure your apps and drivers are exactly how you want them. Use a cloning tool like Clonezilla to create an image of just your root partition, excluding the /home partition. Keep that image safe for when you need to restore your system. As a bonus, you can even convert that image into a bootable self-installing ISO, so you won't need to boot into Clonezilla to do the installation.
Many Linux distributions come with a tool called Timeshift that lets you create snapshots of your OS. It's not as comprehensive as a full disk clone, but it might be close enough for your needs.
Using VirtualBox can simplify some aspects of this process, as you can create a snapshot of a virtual machine, but I understand that it might not be useful if you're concerned about running Linux natively.
