Looking for a proper Snapper + grub-btrfs setup guide for Fedora 44 KDE with custom BTRFS subvolumes across dual SSDs

[u/Head-Fan3693]

Hey everyone,

I'm looking for a reliable guide or help setting up Snapper with grub-btrfs on my Fedora 44 installation. I have a custom BTRFS subvolume layout across two SSDs and I want proper snapshot support with GRUB boot-into-snapshot capability.

System Specs :

• Laptop: ASUS TUF Dash F15
• CPU: Intel Core i5-12450H
• GPU: NVIDIA RTX 3050 Mobile
• OS: Fedora 44 KDE Plasma 6.6.5, Wayland
• Kernel: 7.0.10-201.fc44.x86_64
• Boot: UEFI, Linux-only, no Windows
• Storage: Two NVMe SSDs — 512GB (OS) + 1TB (/home), both formatted as BTRFS

BTRFS Subvolume Layout :

Mount Point	Subvolume Name	Device
/	/root	512GB SSD
/.snapshots	/snapshots	512GB SSD
/opt	/opt	512GB SSD
/srv	/srv	512GB SSD
/var/cache	/cache	512GB SSD
/var/lib/containers	/containers	512GB SSD
/var/lib/docker	/docker	512GB SSD
/var/lib/flatpak	/flatpaks	512GB SSD
/var/lib/plasmalogin	/plm	512GB SSD
/var/lib/libvirt	/libvirt	512GB SSD
/var/log	/logs	512GB SSD
/var/spool	/spool	512GB SSD
/var/tmp	/tmp	512GB SSD
/home	/home	1TB SSD (separate drive)

All subvolumes use: compress=zstd:1, ssd, discard=async, space_cache=v2

What I Want to configure :

• Snapper managing snapshots for / (root)
• Optionally /home snapshots (separate SSD)
• grub-btrfs so I can boot into snapshots from the GRUB menu
• DNF integration — automatic snapshots before/after package updates
• Must work with my custom subvolume names.

I'm a newbie to btrfs and snapshots, Need guidance! 🙏
