Agreed, E makes sense. Hard links can't cross filesystems.

I think it's E. Different filesystems cause issues.

I feel like C is irrelevant. Shell scripts can link fine.

B is also not a problem. Read-only files can link.

Right, A is not an issue. It's about filesystem.

A hidden file shouldn't stop linking, right?

True, D could be a factor too. Permissions matter.

What about D? If you don't own it, can you link?

I think E is the main reason. Different filesystems can't link.

E is definitely a reason, can't link across filesystems.

I remember reading that hidden files don't affect linking, so I doubt option A is the cause. But I could be wrong!

I practiced a question similar to this, and I think a read-only file shouldn't cause an issue. So, I’m leaning towards option E or D.

I'm not entirely sure, but I feel like ownership might play a role here. If I don't own the source file, maybe that's why ln fails?

I think the error could be related to the files being on different filesystems, like option E. I remember something about that in class.
