Duranium is an immutable variant of postmarketOS that uses systemd's image-based OS model: dm-verity verified /usr, A/B slots managed by systemd-sysupdate, LUKS2-encrypted root, and systemd-boot with UKIs. This package ships systemd-repart, systemd-sysusers, tmpfiles, and first-boot service configuration needed at runtime in both the initramfs and the booted system, as well as sysupdate transfer definitions for finding and upgrading images. Build-time repart and sysupdate config lives in the mkosi config repo[1]. The pmOS initramfs is not used. Rather than re-implement partition setup, verity, factory reset, and switch_root in shell script and risk regressions for mutable pmOS installs, an initramfs is built by mkosi containing systemd. This lets the standard systemd initrd machinery handle everything, with no modifications to the pmOS initramfs required. On Android devices, subpartition logic from the pmOS initramfs is essentially copied into a new systemd unit that runs in the initramfs and sets up subpartitions so that they are available to tooling that runs later in the boot process. In the future, this functionality should be moved upstream into systemd. Boot flows: "Normal boot": the verified /usr partition is mounted and the LUKS root partition is unlocked (empty passphrase by default, with fallback to a graphical unlock prompt for user-set passphrases). switch_root hands off to the real rootfs. "First boot": systemd-repart creates the root partition, always as a LUKS volume with an empty passphrase. After switch_root, a first-boot app runs before the display manager to collect a username and password, create the user account, and optionally set a LUKS passphrase. The passphrase can also be changed later via systemd-cryptenroll or cryptsetup. "Factory reset": detected in the initramfs by systemd, which uses systemd-repart to wipe and recreate the root partition. Boot then continues with the first boot flow above. Factory reset can be triggered while booting in the rootfs by starting a systemd unit that configures an EFI variable to signal to the initramfs on next boot.
