Rootstock fails with no error after failing to mount temp image

[TimRedfern]

I'm trying to use rootstock on Ubuntu 11.10

It fails to produce any rootfs tarball.

A nautilus error window pops up during the process saying that the temp image could not be written to.

The command I'm using is:

sudo rootstock -f “Gumstix” -l “gumstix” -p “overo” -n “Gumstix Overo Ubuntu” --seed lxde,gdm,openssh-server –serial ttyS2 -d lucid –locale en_IE.UTF-8

I booted up a 10.04 vmware image and it worked immediately.
