reproduce = """1. Use qemu >= 8.1 (version <= 8.0.x work well)
2. Install `debootstrap` package
3. Run `sudo debootstrap --arch=arm64 bullseye root11-arm64`

This fails to chroot into the system being debootstrapped:

```
$ sudo debootstrap --arch=arm64 bullseye root11-arm64
...

additional = """Failure happens only when debootstrapping "bullseye" with "arm64" architecture.
Older (e.g. <= "buster") and newer (e.g. > "bookworm") distros are deboostrapped OK.
Other (e.g. "armhf" and others) architectures are debootstrapped OK.

Qemu version <8.1 (e.g. 8.0.5 I use in Gentoo or versions in Debian <= bookworm) don't have the bug.

Originally faced the issue with Gentoo host. Recently rechecked with Debian Trixie host."""
