Bug#1079329: systemd(?) still creates /lib64 on arm64

[Luca Boccassi]

Control: tags -1 unreproducible
Control: close -1

TL;DR: I have just spent some time to reproduce this with official
debian images and cannot reproduce this, hence closing as unactionable.

- Download netinst arm64 weekly testing snapshot from
https://cdimage.debian.org/cdimage/weekly-builds/arm64/iso-cd/
- install in an aarch64 VM using virt-manager and run in qemu
- go through the installation process selecting all default options
- boot into installed VM

Everything looks just as you expect it.

For extra safety, I also checked the other official build tool, which
is autopkgtest-build-qemu as it's used by debci.

- apt install autopkgtest vmdb2 ...
- create an image: autopkgtest-build-qemu --architecture arm64 testing autopkgtest-testing-arm64.img
- run an autopkgtest and get a shell: autopkgtest --shell --test-name logind -B . -- autopkgtest-virt-qemu --qemu-architecture aarch64 --dpkg-architecture arm64 --cpus 2 --ram-size 4096 autopkgtest-testing-arm64.img

Same result.

Given this alleged issue cannot be reproduced, given the proposed patch
is obviously wrong and has been rejected by all upstream maintainers as
it breaks other distros and there's no chance it will ever go anywhere,
and there's hence nothing really to be done, closing this bug.
