    <resolution>
        <p>All systemd users should upgrade to the latest version:</p>
        
        <code>
          # emerge --sync
          # emerge --ask --oneshot --verbose ">=sys-apps/systemd-251.3"

          # emerge --sync

        </code>
        
        <p>Gentoo has discontinued support for sys-apps/systemd-tmpfiles, sys-boot/systemd-boot, and sys-fs/udev. See the 2022-04-19-systemd-utils news item. Users should unmerge it in favor of sys-apps/systemd-utils on non-systemd systems:</p>
        
        <code>
          # emerge --ask --depclean --verbose "sys-apps/systemd-tmpfiles" "sys-boot/systemd-boot" "sys-fs/udev"
          # emerge --ask --verbose --oneshot ">=sys-apps/systemd-utils-251.3"
