The previous patch 466266c does not make sense indeed, that is to say, if the SYSTEMD_READY is not recorded in the database, the GOTO="systemd_end" will not be applied.
The IMPORT{db} is actually a matching token, it returns false when there is no SYSTEMD_READY recorded in the database.
The previous patch 466266c tended to inherit the state of SYSTEMD_READY from the database and skip to the end of current rule file. But when the database does not contain SYSTEMD_READY, e.g., the dm-* is not set db_persistent during initrd and the database will be cleared after switching root, the following rules will still be applied not as expected.

Files in this directory contain configuration for systemd-udevd.service, a daemon that manages symlinks to device nodes, permissions of devices nodes, emits device events for userspace, and renames network interfaces. See man:udev(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of service itself. Use 'systemd-analyze cat-config udev/rules.d' to display the effective config.
