Looks fixed now, but what confused me is that r273919 modifies
etc/rc.d/geli.
I've not configured GELI neither in head VM nor stable/10 host.

And what MORE confused me are that...
  *In first reboot (after installworld and mergemaster) at r273922,
   mfsvar problem appeared. (/var/db/ports looked empty.)
   At the moment, r273619:OK -> r273876:NG -> r273902:NG -> r273922:NG.

  *Manfred's workaround helped in following reboot [no other change].
   (And sent my previous mail.)

  *Noticed that r273919 should fix above by your reply, backed out
   Manfred's workaround [no other change] and rebooted, can't reproduce
   the mfsvar problem anymore!
   (With some rebooting test, and updating to r273958.)

Confirmed r273957 and r273958 fixes this. Thanks!
