This should cover cases regarding devices with `OPTIONS+="db_persist"` during initrd->sysroot transition. See: * systemd/systemd#23429 * systemd/systemd#23218 * systemd/systemd#23489 * https://bugzilla.redhat.com/show_bug.cgi?id=2087225 (cherry picked from commit 1fb7f8e)

dm-crypt device units generated by systemd-cryptsetup-generator habe BindsTo= dependencies on their backend devices. The dm-crypt devices have the db_persist flag set, and thus survive the udev db cleanup while switching root. But backend devices usually don't survive. These devices are neither mounted nor used for swap, thus they will seen as DEVICE_NOT_FOUND after switching root. The BindsTo dependency will cause systemd to schedule a stop job for the dm-crypt device, breaking boot: [ 68.929457] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Unit is stopped because bound to inactive unit dev-disk-by\x2duuid-3bf91f73\x2d1ee8\x2d4cfc\x2d9048\x2d93ba349b786d.device. [ 68.945660] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Trying to enqueue job systemd-cryptsetup@cr_root.service/stop/replace [ 69.473459] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Installed new job systemd-cryptsetup@cr_root.service/stop as 343 Avoid this by not setting the state of the backend devices to DEVICE_DEAD. Fixes the LUKS setup issue reported in #23429. (cherry picked from commit cf1ac0c)
On switching root, a device may have a persistent databse. In that case, Device.enumerated_found may have DEVICE_FOUND_UDEV flag, and it is not necessary to downgrade the Device.deserialized_found and Device.deserialized_state. Otherwise, the state of the device unit may be changed plugged -> dead -> plugged, if the device has not been mounted. Fixes #23429.
