    Test Identification POSIX.cmd/pax 1051
    Problem Summary PG4C.00109 This IR claims that an existing fifo should be overwritten.
    Problem Text
    This Test expects that UID and GID of the copied fifo to be
    preserved. However, according to page 584 of the XPG5 XCU,

    "-p string
    .
    .
    o preserve the user ID and group ID."

    GA11 uses the following line

    pax -rw -p am 1051.tmp $lfs_fs/pax1051.tmp

    If -p o is not used then the normal file creation action is
    taken as described in the XPG5 XSH page 570 under O_CREAT
    Test Output

    Review Response
    We recommend this request be refused.

    We believe the test is correct.

    The assertion is testing the following general assertion from
    the POSIX.2 standard.

    When a file that exists is re-created by a POSIX.2 {9}
    application, then the file attributes are set as follows:

    (1) When the file type is a directory or FIFO special file,
    then the attempt fails and the file attributes are not
    changed.

    (2) When the file type is a regular file, then the file is
    truncated to zero length and the st_ctime and st_mtime
    fields are updated. The user-ID, group-ID and permission
    bits associated with the file are unchanged.

    In this case, pax is overwriting the fifo file when it should not be doing do.
    The username being different on the created file is the first indication
    that the file has been changed, since pax has overwritten the file erroneously.
