Solved Where's /dev/md*

I remember that I can access /dev/md* under FreeBSD 11 according to Handbook 17.9 Memory Disks. But it seems that md devices disappear.

Code: 
➜  ~ uname -a
FreeBSD  12.0-RELEASE FreeBSD 12.0-RELEASE r341666 GENERIC  amd64
➜  ~ mdconfig -f foo.iso
md0
➜  ~ mdconfig -a -t swap -s 5m
md1
➜  ~ mdconfig -l
md0 md1
➜  ~ ls /dev/md0 /dev/md1
ls: /dev/md0: No such file or directory
ls: /dev/md1: No such file or directory

I also tried to append an 'unhide' rule for devfs, but it seems not working yet.

Code: 
➜  ~ gpart show

Could you please help me out?

Yes, it's supposed to be. But they were not there. They returned yesterday after rebooting.
