Enable Bcachefs Rollback

Bcachefs is basically quite similar to the Btrfs we know, and if you want to learn more about it, you can read here: Bcachefs Filesystem

Currently, there’s no clear explanation online for how to take snapshots of the / directory system in bcachefs, so we can now enable snapshots for bcachefs by running the bcachefs-rollback hook of mkinitcpio for initramfs.

Thanks to @bathtime for coming up with this method ❤️

Let’s proceed

Watch out!

Currently, this method is used daily by the owner on their personal computer, but there is no guarantee that it will not cause any problems in the future, and since it is not a common method, use it at your own risk!

First, we need to git clone this source before proceeding.

cd /tmp/ && git clone https://github.com/RengeOS/Bcachefs-Rollback-Initramfs

Danger

Do not modify hooks inside the source code if you do not understand how they work, as this could lead to Kernel Panic!

Next, we will install it by building it from source code with makepkg -si.

cd Bcachefs-Rollback-Initramfs/ && makepkg -si

After the package build and installation process is successful, our task is to restart the entire system.

# you can replace reboot to 'systemctl reboot' if not working
reboot
