I've tried to build a bit smaller image after sending the report and in
that do_rootfs it finished successfully. I'll try to re-execute this to
see if I get consistent results.

The bigger image has only few more packages in it, so if this is the
case and smaller always works while bigger always fails I should be able
to quickly find out which package/file is causing this.

I'll check the circular symlinks, I know there are some ptest packages
in the bigger one.

Thanks
