+Unlock Methods
+Method	Description
+TPM2	Use tpm2_unseal with a configured handle.
+GPG	Use an encrypted key file (default: /etc/keys/bcachefs.gpg).
+YubiKey	Retrieve OTP from configured OATH slot BCACHEFS.
+Manual	Fallback prompt if no automated method succeeds.
+
+The module tries each method in order until unlock succeeds.
+
+Systemd Integration
+
+The module now supports systemd units:
+
+systemd-bcachefs-unlock@.service for unlocking devices during boot.
+
+Example to enable root device unlock:
+
+systemctl enable systemd-bcachefs-unlock@dev-sda2.service
+
+
+Note: Systemd support requires udev and initqueue integration. Optional: 80-bcachefs.rules triggers the unlock after device detection.
+
+OpenRC Integration
+
+OpenRC users can enable /etc/init.d/bcachefs-unlock:
+
+rc-update add bcachefs-unlock boot
+
+Configuration Template
+
+A declarative template /etc/bcachefs-tab can be used to specify devices, keys, and unlock methods:
+
+# Format: UUID=<uuid> DEV=<device> KEY=<file|tpm2|yubikey> METHOD=<tpm2|gpg|yubikey|manual>
+UUID=abcd-ef12-3456 DEV=/dev/sda2 KEY=/etc/keys/rootfs.gpg METHOD=gpg
+UUID=1234-5678-abcd DEV=/dev/nvme0n1p3 KEY=tpm2:auto METHOD=tpm2
+
+
+Copy /etc/bcachefs-tab.new to /etc/bcachefs-tab and edit accordingly.
+
+Installation
+Dracut Module
+make install-dracut
+dracut --force --add 90bcachefs
+
+Systemd Unit
+make install-systemd
+systemctl daemon-reload
+systemctl enable systemd-bcachefs-unlock@dev-sda2.service
+
+OpenRC Script
+make install-openrc
+rc-update add bcachefs-unlock boot
+
+Template
+make install-tab
+cp /etc/bcachefs-tab.new /etc/bcachefs-tab
+
+Notes
+
+The root of the bcachefs filesystem is always available at /.bcachefs for additional mounts.
+
+Additional subvolumes must be mounted manually in /etc/fstab or via post-boot scripts.
+
+Works with both encrypted root and data volumes.
+
+Tested on both OpenRC and systemd setups with TPM2/GPG/YubiKey unlock support.
