To be more precise: You're trying to put your swapfile on the internal drive.

I got a similar setup and the same problem.

And here's the problem: is /local already mounted when mach_swapon tries to put
the swapfile on it ? I strongly suspect it isn't. At least mine wasn't in a 
similar setup.

To summarize: your internal drive is very likely not mounted when you're
trying to install your swapfile on it. It is mounted later by the automounter.
Solution: create an appropriate fstab entry for your external disk so it will
be mounted at boot time (in /etc/rc.boot if i remember correctly) before
mach_swapon gets called. This worked for me.

hope that helps
