after further investigation, and applying this diff to the source package fetched with apt source lxc:

it now works with the log saying this:

… but I have absolutely no idea what is actually going on here. It says Detected rootfs type "overlay" directly above, but then rootfs->bdev_type is NULL?!?
checked again with HEAD (208161eb764305a9d78190b3a5ca1784146d58bc), behavior is still this:

This bug also affects Debian, and has been reported separately: reportbug: lxc-copy --ephemeral always fails
As best as I can tell, rootfs->bdev_type isn't actually being set anywhere, other than if it comes from a config file (set_config_rootfs_path() in src/lxc/confile.c).
I've come up with this small patch that seems to work, although I don't know if it's the best way to fix this:
