Hi,

This was during the “removing unused link” phase, right?

What does “uname -r” return?

This is most likely an issue with the ancient kernel being used.

It would be nice if you could try running a C program that does
something like this:

	struct statx st;
	if (statx(AT_FDCWD, "/",
		  AT_SYMLINK_NOFOLLOW | AT_STATX_DONT_SYNC,
		  STATX_SIZE | STATX_NLINK, &st) == -1)
          printf ("failed: %m\n");

It should fail similarly.  Then you can try commenting out
AT_STATX_DONT_SYNC and see whether it fails.

Let me know how it goes!

Thanks,
Ludo’.
