refresh partition table

[David Henderson]

Greetings everyone.  I'm doing some work with a hard drive within a 
busybox based OS and if the partition table gets modified I'd like to 
have it refreshed.  Using other distro's I can issue the 'partprobe' 
command and it does just that.  The problem is, busybox uses mdev and it 
appears as though 'partprobe' relies on udev.  I checked the options 
available to mdev, but see that it can only take one parameter (-s 
during bootup).  I don't want to reload the entire contents of /dev, 
just the partition table for a drive.  Anyone have any ideas on how to 
accomplish this?

Thanks,
Dave
