This is my fork of [easy-arch](https://github.com/classy-giraffe/easy-arch), a **script** made in order to boostrap a basic **Arch Linux** environment with **snapshots** and **encryption** by using a fully automated process (UEFI only).
This fork comes with various security improvements and fully working rollbacks with snapper. I do submit some of the changes here back to upstream as well.
The Secure Boot script can be run post installation to automate the process of generating your own keys and setting up Secure Boot described at https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot. Please make sure that your firmware is in Setup mode and the TPM is disabled.
Currently, there is an problem where GRUB requires tpm.mod to be included for signature verification, but if tpm.mod is included and the TPM is enabled it will also attempt to do Measured Boot, breaking the Arch Linux snapshots menu created by grub-btrfs. I have yet to find a solution for this issue.
1. Snapper rollback <number> works! You will no longer need to manually rollback from a live USB like you would with the @ and @home layout suggested in the Arch Wiki.
2. You can boot into a readonly snapshot! GDM and other services will start normally so you can get in and verify that everything works before rolling back.
3. Automatic snapshots on pacman install/update operations
4. Directories such as /boot, /boot/efi, /var/log, /var/crash, /var/tmp, /var/spool, /var/lib/libvirt/images are excluded from the snapshots as they either should be persistent or are just temporary files. /cryptkey is excluded as we do not want the encryption key to be included in the snapshots, which could be sent to another device as a backup.
5. GRUB will boot into the default BTRFS snapshot set by snapper. Like on SUSE, your running system will always be a read-write snapshot in @/.snapshots/X/snapshot.
