}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
I use snapper. It takes snapshots not only triggered by pacman hooks but also on an interval or manually.
manjaro does this with timeshift. i think opensuse does as well.
The AUR package btrfs-autosnap does this. You define which subvolumes need to be snapshotted and how many it should keep of each. It adds a pacman hook that then takes a snapshot before updating.
I'm also on EndeavourOS and used this tutorial to do exactly that.
All you should have to do is
yay -S snapper-support btrfs-assistant
