In libguestfs we already work around qemu changing its user when we are running as root: https://github.com/libguestfs/libguestfs/blob/0991b4dc2124a8d6c3d232663ea3473a0c78f81f/lib/tmpdirs.c#L202 However I think because passt is creating the file, it cannot write into the 0755 directory. Honestly (just as with libvirt / qemu) unilaterally changing the user ID when running as root is not helping anyone nor adding any security. As for working around the bug, just don't run virt-customize as root. There's no need to run guestfs tools as root, unless for some reason you need to edit a disk image which is only accessible by root.
