So, I removed virtual/libgudev and libgudev and got an existing
preserved libs for that library, but the world update still wanted to
put it back.  Then I changed systemd's use flags to say -gudev.  So
portage was almost happy, (it did want to put back libgudev, but it was
not a block), but the one remaining block  is sys-apps/sysvinit -- I
removed that, but portage wants to put it back and it still has the
bloc as seen  below
[blocks B      ] sys-apps/sysvinit ("sys-apps/sysvinit" is blocking sys-apps/systemd-219_p112)

Total: 81 packages (64 upgrades, 1 downgrade, 10 new, 2 in new slots, 4 reinstalls), Size of downloads: 274,456 KiB
Conflict: 1 block (1 unsatisfied)

 * Error: The above package list contains packages which cannot be
 * installed at the same time on the same system.

followed by the same systemd messages as before.
