The issue #12953 is caused by the following: On switching root, - deserialized_found == DEVICE_FOUND_UDEV | DEVICE_FOUND_MOUNT, - deserialized_state == DEVICE_PLUGGED, - enumerated_found == DEVICE_FOUND_MOUNT, On switching root, most devices are not found by the enumeration process. Hence, the device state is set to plugged by device_coldplug(), and then changed to the dead state in device_catchup(). So the corresponding mount point is unmounted. Later when the device is processed by udevd, it will be changed to plugged state again. The issue #23208 is caused by the fact that generated udev database in initramfs and the main system are often different. So, the two issues have the same root; we should not honor DEVICE_FOUND_UDEV bit in the deserialized_found on switching root. This partially reverts c6e892bc0eebe1d42c282bd2d8bae149fbeba85f. Fixes #12953 and #23208. Replaces #23215. Co-authored-by: Martin Wilck <mwilck@suse.com> (cherry picked from commit 75d7b5989f99125e52d5c0e5656fa1cd0fae2405)
