Linux

Okay any time I mention this product I get roasted but I don't care because I like it. There is a program called aptik and basically it backs up all your settings and home folder and then can be restored if you need to reinstall. https://store.teejeetech.com/product/aptik/

It's a one time purchase. I bought my copy like maybe almost 10 years ago and still use it. I used to have a script that I would maintain manually for this sort of thing but this is much easier. I also like that it will update strings and stuff for you when going from one version of a distro to another or between distros. You can also easily go in and uncheck things if you don't want them or only revert certain parts of the backup and not others. it has 100% saved my butt a few times especially where I had some weird config on a piece of software and after a restore it worked just like before. In my opinion this is also a better option than a diskimage because of the customization of the restore and the fact that you can do it I guess my biggest issue with it is it's not free software which is kind of annoying however it's just one dude and the license is very bare bones so it's not like he is trying to get away with anything with this tool.

When I was doing it I started from scratch, you can generally keep your home directory intact between distros though, settings and data stay

I prefer to do it clean and manually transfer files, because I usually don't want a copy paste of my previous setup. For files that are just, for lack of a better way of putting it, personal storage (ie the files that are not dotfiles in my home directory, eg pictures and documents etc), they are on a Nextcloud.

You can backup you home-directory and add it back into the newly installed OS. Some of the more dedicated distro-hoppers will even have the home-directory on a separate partition, which they don't overwrite during installation and rather just mount into the new OS.

The home-directory contains all your music, pictures, add-ons and portable software. It also contains your configurations under ~/.config/ and local files of applications under ~/.local/.
After you've reinstalled, you won't have all the same applications installed, but once you reinstall them, they should pick up the configuration from those folders and work as you expect. Sometimes, your new distribution/installation might use different versions of that particular software, so it's not guaranteed that everything works perfectly, but it does work pretty well.

What do you do with all your music, pictures, addons, portable software?

I sync them to a NAS using Syncthing. Not just when switching but always. Already saved my ass several times.

Or debian with distrobox and you have all the benefits of all the distros at the same time lol

I used to just do it from scratch each time but when I went to Debian years ago I didn't need to distro hop again as it is just a rock solid distro and it just keeps going. If migrating a machine I usually just copy the home dir after ive set up the machine.

I don't distrohop much these days because I'm happy with where I am. But I actually enjoy having a clean start once in a while; going back and experiencing the defaults for a time helps clarify which customisations are actually really useful and which ones I'm just stuck in a rut with which happens a lot more than I usually expect. Of course I back up all my data/media and move that across, but configurations I like to approach with a clean slate. It's quite freeing to know that I can just wipe and reinstall my system at any time without much difficulty.

All my stuff is on a network drive (movies and other big files). All configuration of apps is in git (their config files).

Makes it easy to start over.

I just reinstall apps I need, it's so simple with Linux and package managers handling it all.

I don't. I switched to Bazzite after using EndeavourOS for a while, and those are the only two I've used. I see no reason to ever go back from Bazzite though.

With immutable distros you can "rebase" very easily to a different immutable distro with literally one command. I haven't really messed with it yet, but it seems pretty straightforward.

I used to distrohop in the past. It's nice to have a USB stick from which multiple distros can be booted. I used YUMI by flashing on a 16 Gb USB stick. After that it's a simple case of downloading your .iso of choice, clicking and dragging it into the YUMI drive.

There was a Ventoy craze in the middle. I have never used it, so I cannot attest to its experience.

What I generally check in a distro:

1. The programs that come built with the distro. Over a period of time, I stick to one distribution (say, Linux Mint), but install the software that I like from another distro (Say the Clipboard application from MXLinux).
2. How quickly the distro installs.
3. The software version in the distros repository. For example, MXLinux repos tends to be more up to date compared to Mint.
4. How the distro customises the Desktop environment. Example, the way cinnamon and XFCE are customised in Mint and MXLinux respectively is very different from the base install of these DEs. That quality of life addition can really change your opinion on using the distro as a whole if you are a newcomer.

So many settings I changed, applications I installed, configured and forgot about.

Yeah this gives me existential dread as well. This is why my next distro will probably be NixOs. Their distro's philosophy is designed off of a configuration based environment.

That hypothetically solves all those problems, although I'm sure it adds some new ones of its own.

I don't distrohop but I do backup my home folder which also contains most of my settings & tweaks. I also keep a simple list of all the apps/packages I have installed in a text file.

I had to reinstall a few weeks a go (new SSD) and it took me maybe 10 minutes to make the base install + all my apps ( 'sudo apt install' with a copypaste of my list of apps), and then the time required to copy my home folder too (which was fast). Add to that the couple apps I have to manually install (like Filen for the cloud, Bitwarden for passwords) and that's it. It's really one of the things I appreciate since I switched to Linux (coming from Mac where a fresh install now takes... a lot of wasted time).

I use virtual machines and live usbs to try out distros when I'm thinking of a change. That gives you a chance to get a feel for the design philosophy of a distro and whether it works for you.

As others have said, back up is really important. You can back up a lot of settings and preferences and bring them to a new distro. They're stored in your home directory in folders like .config and .local.

I keep a back up of my /home folder. I'm also a KDE main so use Konsave to specifically back up my KDE theme and settings.

If you are at the point of moving then that's the time to make backups ready to restore. Also get a list together of the apps you want to keep so you can get set up quickly in a new distro.

Also another habit to get in to is backing up any major config changes into your Home folder for later reference. Even if you don't use the exact same file it can be useful to have somewhere that reminds you what you tweaked or did to get the system how you wanted it. For example I keep copies of my fstab file (just for reference!), and config files for programs I put in /opt amongst other tweaks I've made.

I also save Web pages which have specific tips I used in Linux configs - really helpful if you ever need to go back and do something again. I write txt files on some complex or niche things to remind me exactly what I did as you're unlikely to remember things you've only done once. These are two habits it's worth getting into - saves so much time hunting for how to do things when you need to, even if you're not moving distros.

All these things together make switching distros much easier should you want to do it.

By far the most important thing I've done is created a list of all the package names. With just one command, I can reinstall all my apps.

The second most important thing I've done is created a long list of gsettings/dconf commands that configure Gnome to my liking.

I've also moved most of my user data off my OS drive to removable drives. But I don't have my home on a separate drive since I don't want to share that across different distros since they configure things differently. It's also just a lot easier to not have a separate home.

Apart from that, the script I have also copies over some config files, sets my hostname, sets flatpak overrides.

As someone who distrohoped quite a bit, let me give you some advice:

• Try the new distro in a VM first.
• Configure your distro as you want and put all the commands you used in a script to use when you make the switch.
• Ask your self, what do i get from distrohoping? Is it really worth it?
• Create a dotfilles git repo with all of your configs. Create a script to install your dotfiles easily. (Either by copying them to .config or creating symlinks)

Remember that, at the end, linux is linux, remember that you can customize you distro to look exactly like the fancy one you saw.

A way to distrohop could be a virtual machine. That way you aren't "sacrificing" your current install.

If you choose to reinstall, try to document all the changes you are doing and why. See if you can automate the changes. That way you can always get back to a desired state with minimal input on your end.

I don't really distrohop alot but this is what makes me distro hop and this is what i look in a disto.

1. What packages does the official repo have.
2. How frequently the distro breaks (Low to no breakage prefered)
   3.How old the packages are.

Honestly, why switch distros? I switch DEs from time to time
