Version 252-rc1
    
    ... (for details see https://raw.githubusercontent.com/systemd/systemd/v252-rc1/NEWS)
    
    systemd-pcrphase and systemd-measure and initrd-* units are moved to systemd-udev.
    systemd-udev should be part of the initrd, and those tools don't make much sense
    in systems without hardware (i.e. containers). (systemd-measure could possibly be
    useful, but we can always move it back if there's a good reason.)
