Is there a way to automatically take a btrfs snapshot prior to upgrading? (programming.dev)

I've seen some tools that do things like take snapshots periodically and ones that add snapshots to grub, but not this specifically. Does something exist?

This will probably be on EndeavourOS, not Arch directly, if it matters.

I don't know the details, but CachyOS uses a pacman hook to do exactly that, so it's possible. It looks like there are AUR packages to do the same thing, but I haven't looked at them

Does it do this out of the box? CachyOS is another option on my radar and that might push it over the edge for me over EOS.

Yep, as long as you use btrfs during the install and select snapper support

Just installed CachyOS and chose btrfs when installing, but it never asked about snapper. Maybe I need to do it manually.

If you open cachy hello, you'll see an option to install snapper support there. I should also add, you need to use grub for the boot images to work when you do a kernel upgrade

Awesome! I installed it. Hopefully if something goes wrong I should be good. And yes, I used Grub!

You can always test it by booting off a backup image. If it works, you have peace of mind, and you can just reboot again from the correct image
