Subject: Strange Issues Executing Binaries Copied via Flash Drive

Dear Alpine devs,

I am encountering strange issues trying to get the xmrig binary running on my system on a clean, stock install.

The sequence of events:

1. I download the release archive on my macbook running macOS 12.6.3 : https://github.com/MoneroOcean/xmrig/releases/download/v6.19.0-mo1/xmrig-v6.19.0-mo1-lin64-compat.tar.gz
2. I extract it, and then cp the files to a FAT32 MBR formatted flash drive.
3. I eject the drive in Finder, remove it from the macbook and plug it into my Alpine box.
4. I `mount` it to `/mnt`, use cp to copy the files to my /root directory.
5. I then try to execute the binary with `./xmrig`, only to run into "-ash: ./xmrig: not found".
6. Bash reports "bash: ./xmrig: cannot execute: required file not found".
7. Zsh reports "zsh: no such file or directory: /root/xmrig"

But clearly, the executable exists. `cp` put it there, `ls` shows it and `cat` can read it.

I gave up and tried to directly download it with `wget https://github.com/MoneroOcean/xmrig/releases/download/v6.19.0-mo1/xmrig-v6.19.0-mo1-lin64-compat.tar.g <https://github.com/MoneroOcean/xmrig/releases/download/v6.19.0-mo1/xmrig-v6.19.0-mo1-lin64-compat.tar.gz>`, but I suppose the busybox wget has some kind of disability, because it fails with a 404.

What's happening here? I am entirely out of my depth, any guidance is appreciated.

Thanks,
Anant Prem Joshi.
