Tracked down the cause to the Docker host, which runs on jammy, not
knowing about fchmodat2(). The syscall should normally return ENOTSUP
when called with AT_SYMLINK_NOFOLLOW on Linux, but the Docker seccomp
profile causes it to return EPERM, which confuses tar(1). Closing.
** Changed in: tar (Ubuntu)
Status: New => Invalid
