If you use the UFS ID label instead you don't need to reboot because you
don't modify the superblock :)
You can find the ID with..
line=`dumpfs 2> /dev/null $1 | head | grep superblock\ location`
# dumpfs doesn't print leading 0s
echo $line | sed -nEe 's/superblock location.*id.*\[ (.*)(.*)\ ]/printf %0x $((0x\1 << 32 | 0x\2))/p'
(in an sh like shell)
