Building docker image fails

Hi all,

I'm trying to build the Arch Linux docker image, and it's currently failing (output below) :

Re: Building docker image fails

Did some further testing and it appears this step is producing a 0 byte file:

cd /home/admin/custom-arch/base/archlinux-docker/output; xz -9 -T0 -f base.tar; sha256sum base.tar.xz > base.tar.xz.SHA256

Specifically:

xz -9 -T0 -f base.tar

if I run it on it's own, with verbose output I get the following (it fails):

admin@system output]$ xz -9 -T0 -f base.tar -v
base.tar (1/1)
Killed%          4.2 MiB / 18.9 MiB = 0.220   5.7 MiB/s       0:03 

Edit:

removing -T0 appears to resolve the problem, by the looks of things this isn't necessary anyway.
