When attempting to run lxc-copy -e -n build_ubuntu1804_amd64 -N TEST -o logfile -l DEBUG, the following failure is reported in logfile:

lxc-copy build_ubuntu1804_amd64 20220913113949.910 DEBUG    storage - storage/storage.c:get_storage_by_name:209 - Detected rootfs type "overlay"

strace has this to say:

openat2(-9, "overlay:/var/lib/lxc/build_ubuntu1804_amd64/rootfs:/var/lib/lxc/TEST/overlay/delta", {flags=O_RDONLY|O_NOFOLLOW|O_CLOEXEC|O_PATH, resolve=0}, 24) = -1 EBADF (Bad file descriptor)

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?!?

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:
