This does remove /dev/gptid, but /dev/gpt did not reappear.

Setting that to 1 still does not cause the /dev/gpt directory to appear. 
What's odd about this is that it did work on 8-stable recently.  A 
system here with i386 8-stable from January 13 has both sysctls enabled 
and both gpt and gptid directories in /dev.  So does an i386 9-stable 
from February 9.  The system where they aren't appearing is amd64 from 
Tuesday (March 6).

None of these systems have ZFS filesystems.
