Which debian rootfs are you using?
I just wanted to inform you that my work on the debian buster rootfs is now nearly finished and it boots to ssh, the lxc container starts and libhybris also works.
I have some pre-built one around here: https://archive.org/download/halium-debian-rootfs/halium-debian-rootfs_20171024.tar.gz and the source for the rootfs-builder has moved here: https://github.com/debian-pm/rootfs-builder.
