Systemd fails to install on Noble arm64

[Joshua]

Hello! When trying to bootstrap a new arm64 rootfs using the upcoming Noble release the systemd post-installation script will fail. Please see the file debootstrap.log attached for package install logs.

To reproduce:
$ sudo debootstrap --no-merged-usr --arch arm64 noble rootfs http://ports.ubuntu.com/ubuntu-ports

Description: Ubuntu 20.04.6 LTS
Release: 20.04

systemd:
  Installed: (none)
  Candidate: 255.2-3ubuntu2
  Version table:
     255.2-3ubuntu2 500
        500 http://ports.ubuntu.com/ubuntu-ports noble/main arm64 Packages

I ran into the same problem, but I found that it should work if bootstrapping from 22.04.

The problem appears to be due to the version of QEMU available for 20.04. The user mode emulation doesn't support OFD (open file description) locks according to: https://lists.gnu.org/archive/html/qemu-devel/2020-08/msg06566.html

It looks like that was fixed in QEMU 5.1. Since 22.04 carries QEMU 6.2, I was able to work around this issue by manually upgrading the qemu-user-static package to the 22.04 version. This actually works on 20.04 because the binaries are statically linked.

Is this still an issue? My understanding was that there was some debootstrap issue, but that this is not actually related to systemd. Not sure if anything was fixed though.
