Copies of the same file aren't included

[sfxworks]

Description

Files of the same copy with different names do not get stored.

Trying to store both a default initramfs img and fallback img into a UOR collection for booting.

    /mnt/iso/arch/boot/x86_64  sha1sum initramfs-linux-hardened.img                                                                             INT ✘ 
243bc6a8392b9c1d316cf2f08e5b0fe0ed5b2379  initramfs-linux-hardened.img
    /mnt/iso/arch/boot/x86_64  sha1sum initramfs-linux-hardened-fallback.img                                                                        ✔ 
243bc6a8392b9c1d316cf2f08e5b0fe0ed5b2379  initramfs-linux-hardened-fallback.img

As we see they're the same file, but with different names.

They are not included in the final bundle

uor inspect --reference go.registry:1338/archiso:latest | grep initramfs-linux-hardened
arch/boot/x86_64/initramfs-linux-hardened-fallback.img  sha256:6a7d6e2ed9cbc8b98af3ba128290f1a6f93c25f228a9c81fb622c7444669493d  31808830   application/zstd

UOR definitely sees these files as it passes over them when making the collection

newfstatat(AT_FDCWD, "/mnt/iso/arch/boot/x86_64/initramfs-linux-hardened-fallback.img", {st_mode=S_IFREG|0444, st_size=31808830, ...}, AT_SYMLINK_NOFOLLOW) = 0
newfstatat(AT_FDCWD, "/mnt/iso/arch/boot/x86_64/initramfs-linux-hardened.img", {st_mode=S_IFREG|0444, st_size=31808830, ...}, AT_SYMLINK_NOFOLLOW) = 0
newfstatat(AT_FDCWD, "/mnt/iso/arch/boot/x86_64/vmlinuz-linux-hardened", {st_mode=S_IFREG|0444, st_size=9758880, ...}, AT_SYMLINK_NOFOLLOW) = 0

Steps to reproduce the issue:

1. Take a file and copy it
2. include that file in the same directory (or a different one?)
3. make a collection and notice one isn't there

Describe the results you received:
