[pve-devel] Compiling PBS on arm64

[Kamil Trzciński]

OK. If anyone is interested, a little hacky, but works:

1. I was able to compile (after minor patching) without having to rebuild
the whole dependency tree
    as required by Debian, instead using `crates.io`. It builds on a Debian
Bullseye as it was simpler
    and required basically no backports

2. I did use stock `debcargo`, but had to include patches to add `debian/*`
files in some cases.
    This is suboptimal, but it was the fastest way to have something
working. Ideally a mentioned `debcargo`
    should be used to create this glue between Rust and Debian

3. It compiled a minimal PBS for `amd64` and `arm64v8`. `amd64` compiled
natively, where for
    compiling `arm64v8` I used `qemu-user`. It took a few hours for this to
finish

4. It builds a very simple Docker image that can be easily run via
docker-compose. I was successful
    running a bunch of backups from my Home PC to my NAS running on
RockPro64 (ARM64)

5. All details and precompiled images are here:

    - https://github.com/ayufan/pve-backup-server-dockerfiles
    - https://hub.docker.com/repository/docker/ayufan/proxmox-backup-server

6. I plan to occasionally update it to the newer version and use it
personally for backuping my personal PVE
