tripwire and device numbers

While getting a box ready for deployment, I noticed on two occasions, 
I would get some exception reports flagging all files as the 
underlying device number through reboots had changed.  Is this 
"normal" for Tripwire and FreeBSD ? (RELENG_7)

The file system is on
da0 at twa0 bus 0 target 0 lun 0
da0: <AMCC 9650SE-2LP DISK 4.08> Fixed Direct Access SCSI-5 device
da0: 100.000MB/s transfers
da0: 238408MB (488259584 512 byte sectors: 255H 63S/T 30392C)
SMP: AP CPU #1 Launched!

eg.

Rule Name: Local files (/usr/local/sbin)
