I have an almost identical perl script that I have used for devd
debug in the past. I had completely forgotten about it.

!system=DEVFS subsystem=CDEV type=CREATE cdev=ufsid/4c43cc21c711100c
!system=DEVFS subsystem=CDEV type=CREATE cdev=ufs/Scratch
!system=DEVFS subsystem=CDEV type=CREATE cdev=ufsid/4c43cc21c711100cd
!system=DEVFS subsystem=CDEV type=CREATE cdev=ufs/Scratchd
!system=DEVFS subsystem=CDEV type=DESTROY cdev=ufs/Scratch
!system=DEVFS subsystem=CDEV type=DESTROY cdev=ufsid/4c43cc21c711100c
!system=DEVFS subsystem=CDEV type=DESTROY cdev=ufs/Scratchd
!system=DEVFS subsystem=CDEV type=DESTROY cdev=ufsid/4c43cc21c711100cd

While all of these activities are related to ufs and ufsid, the device
is re-mounting the /dev/da0s2d partition. Is the 'd' partition possibly
triggering this?
