I build small, focused Linux utilities for Debian, Ubuntu, and their derivatives, with an emphasis on Btrfs, Snapper, GRUB, and system recovery.

My current work focuses on improving the native Btrfs and Snapper experience without replacing the tools and workflows already provided by the distribution.

BootPrep is my flagship project.

BootPrep is a lightweight boot preparation layer for Debian, Ubuntu, and their derivatives using Btrfs and Snapper.

It is designed to work alongside native tools such as Btrfs, Snapper, GRUB, and grub-btrfs, handling the additional boot preparation needed after snapshot operations.

BootPrep is part of a growing collection of focused utilities. Each project has a single responsibility and can be used independently or together.

• snapshot-chroot – Creates a recovery chroot from a Btrfs/Snapper root snapshot, automatically detecting the last successfully booted snapshot.
• cleanup-bootstrap-root – Safely cleans the original bootstrap @ root while preserving its Btrfs subvolumes.
• dpkg-pre-post-snapper – Creates descriptive Snapper pre/post snapshots around Debian package transactions.
• add_subvolumes – Converts selected root and home directories into independent Btrfs subvolumes.
• add_updategrub-service – Installs a systemd service that runs update-grub during system shutdown.

I prefer tools that are:

• Focused – one clearly defined responsibility.
• Native – build on existing Linux components instead of replacing them.
• Discoverable – detect the system's actual configuration instead of relying on unnecessary hard-coded assumptions.
• Safe – validate the environment before making filesystem or boot-related changes.
• Composable – useful independently, but able to work together as part of a larger workflow.

If you're working with Debian, Btrfs, Snapper, GRUB, or snapshot-based system recovery, take a look at BootPrep and the companion projects above.
