I can reproduce this with sandbox-2.34 on an arm64 EC2 server.
This is a really weird bug. The ptrace code in sandbox is definitely catching the unlinkat syscall, but the kernel still removes the file. arm64 seems to be unique in that the kernel provides unlinkat(), but does not provide unlink(). libc provides unlink() as a library function that calls unlinkat(). I'm not sure if this is related to the problem. Anyway, I suspect there is something wrong with the sandbox code that modifies the system call. Either that, or we have run into a kernel bug.
Apparently this test has never worked on arm64. https://gitweb.gentoo.org/proj/sandbox.git/commit/?id=3e60745c278248baa9cac3da0b4ed3f7dcd96501 We should probably XFAIL it for now.
