From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If they are all installed in the same wine prefix you could back up everything in one go by archiving the ".wine" folder in your home. that will include all applications installed in wine and all settings for those applications.
if you want to separate them into one archive per app you should look into wine prefixes, otherwise you would need to identify every folder a given app created during installation and archive those together manually, which can be very tedious.
What about graphics drivers? What if the desktop has an Nvidia GPU and the steam deck is AMD. Would that even matter?
No, you can copy wine prefixes around all you want. You may have to adjust the graphics settings in the games though.
Makes sense. I wouldn't want to have all of my games in one wine prefix. I would like to keep them separate like steam/proton does. From looking it up, it seems the issue is that there is a lot of duplicate data that would need to be deduplicated. Steam supposedly does symlinks to solve this. But, if the symlinks points to /home/user/ as the base then that would break on /home/deck.
If you have any experience with Lutris/bottles. Do they do separate wine prefixes? If so, how do they handle it?
Lutris uses separate prefixes and doesn't do any deduplication. You will need a separate tool for that or just use a filesystem like btrfs that supports deduplication.
I've never used bottles, so I don't know how it handles deduplication.
Thanks for your help!
