I rebooted the machine with disabled disk_ident and gptid but nothing 
changed:

# ls -1 /dev/ada*
/dev/ada0
/dev/ada1

# ls -1 /dev/gpt
ls: /dev/gpt: No such file or directory


# zpool list -v | cut -c1-28
NAME
sys
   mirror-0
     diskid/DISK-Z3010G8Vp3
     diskid/DISK-Z302YC90p3
tank1
   mirror-0
     diskid/DISK-Z3010G8Vp5
     diskid/DISK-Z302YC90p5


# sysctl kern.geom.label
kern.geom.label.disk_ident.enable: 0
kern.geom.label.gptid.enable: 0
kern.geom.label.gpt.enable: 1
kern.geom.label.ufs.enable: 1

  # ls -1 /dev/diskid/
DISK-Z3010G8V
DISK-Z3010G8Vp1
DISK-Z3010G8Vp2
DISK-Z3010G8Vp3
DISK-Z3010G8Vp4

DISK-Z302YC90p2
DISK-Z302YC90p3
DISK-Z302YC90p4
DISK-Z302YC90p5

Why are diskid aliases created if they should be disabled by sysctl 
kern.geom.label.disk_ident.enable?

Kind regards
