Apple Hard Drive

I've got my boot disk partitioned in 3 partitions, one of them I was using as the mount point for OS X.  Having installed OS X successfully on my 2nd partition, I wiped the third clean.  Is there any way to nondestructively rejoin these partitions in single user mode? (ie, Does resizeVolume have an appropriate comand?)

I was about to say 'yes it's easy' when I realised I'd accidentally stepped into an Apple thread, at which point I walked away chuckling and saying 'Lol Macusers'

Uhh. Do you have a spare hard drive with room? You can make a copy of the drive and restore it later, perhaps with the commands in this article: http://www.macosxhints.com/article.php?story=20060216225428857

If you want to truly resize\merge your partitions, I believe Leopard's disk utility does it, so maybe torrent that and run it from the install CD. And if Linuxfags like >>2 are to be believed, a proper partition resizing utility is only a livecd, ten hours of compiling, a two-hundred-line config file, three hours of resolving dependencies and a cute Tux picture on the boot screen away.
