    Test Suite VSU version 5.1.1
    Test Identification CAPI.os/files/mknod 19
    Problem Summary TSD4U.00300 The tests fail on systems which do not give precedence to EROFS over ENOSPC
    Problem Text
    The tests fail because the filesystem used is out of inodes. When the test
    tries to create a new inode, the file system returns ENOSPC, the test expects
    EROFS.

    The problem is an issue of precedence between EROFS and ENOSPC. The
    file system is mounted read-only but is also out of inodes because
    it is using VSX_NOSPC_DEV. When an attempt is made to create a new
    file, the call could get EROFS or ENOSPC, depending on which
    condition the implementation checks first. The POSIX and UNIX
    standards do not specify any precedence between these errors.

    Test Description:
    Base Required Deviance
    EROFS in errno and return -1 on a call to int mknod(const char *path,
    mode_t mode, dev_t dev) when the file specified by path resides on a
    read-only file system.

    Test Description:
    Base Conditional Conformance
    If the implementation supports the AF_UNIX communications domain and a
    socket type:
    EROFS in errno and return -1 on a call to int bind(int socket, const
    struct sockaddr *address, socklen_t address_len) when the address
    family of the socket is AF_UNIX and address would reside on a read-
    only filesystem.
