I have a fully updated f15 x86_64 system in which I have mock installed. I set up a mock chroot for building f15 x86_64 which appeared to work normally, and then inside the chroot I installed spin-kickstarts as usual when preparing to do a build. I then set up a fairly standard f15 x86_64 pungi build, but towards the end of the process it failed. In the chroot terminal window the last few lines were: [100%] erasing xorg-x11-server-utils-7.5-5.fc15.x86_64 [100%] erasing yum-3.2.29-6.fc15.noarch [100%] erasing zenity-3.0.0-1.fc15.x86_64 cannot erase fedora-15-x86_64-logos: Package not installed cleaning up python files creating the initrd creating required directories copying kernel image compressing the install tree creating efiboot image with kernel mount: Could not find any loop device.

However I don't know how to rectify this? Is there a critical package that I am missing? Is there a bug in the lorax package which means that an updated version needs to be installed (from updates-tesing possibly)? Any help would be appreciated.
