Sorry, that was a typo. I did remove /tmp/.guestfs-* Hmmm. I did a build on Monday, which matches the time stamp of /usr/lib, and a build yesterday which matches the timestamp of /usr/local/lib. I can't think of any reason for the difference. cpio on /usr/local/lib/guestfs/supermin.d/init.img gives the same output as on /usr/lib/guestfs/supermin.d/init.img. I moved /usr/lib/guestfs out of the way with no noticeable difference, but not to say its presence could be indicative of other weirdness. Below is the log from a run right after removing /tmp/.guestfs. new guestfs handle 0x9d2f958 ===== Test starts here ===== LIBGUESTFS_DEBUG=1 library version: 1.8.4 guestfs_get_append: (null) guestfs_get_autosync: 1 guestfs_get_memsize: 500 guestfs_get_path: /usr/local/lib/guestfs guestfs_get_qemu: /usr/bin/kvm guestfs_get_verbose: 1 Launching appliance, timeout set to 120 seconds.

Note that in your original trace[1] the appliance had already been cached, so w didn't get to see any errors from the build.  Therefore if it is still failing after removing the cached appliance, post the output of libguestfs-test-tool on the first run after doing that 'rm -r'. This looks good to me, except that from your original trace[1] the path would have been /usr/*local*/lib/....  Is it odd that this path has changed?  Are you running matching versions of the library and the appliance?  Do you have another version installed from some previous attempt?
