NFS Problems in Fedora 33

    Hi, all,
    Since upgrading to Fedora 33, I am having some
        problems accessing files on NFS shares. I should say first that,
        immediately after the upgrade, the shares would not mount at
        all. I was getting the error:
    mount.nfs4: Operation not permitted when
        mounting NFS device
    even when attempting to mount manually.
        Eventually, I found some info online that suggested mounting
        manually as root, which created some symlink or other. After
        that, the shares would mount automatically at boot.
    However, now, as I said, I have problems
        accessing files on said shares. The directory ~/files/ is an NFS
        mount from a server running CentOS 7. My LyX user directory is
        at ~/files/config/lyx/
          (symlinked from ~/.lyx/). LyX refuses to start, blocking at a
          call to 

      lockf(fd, F_LOCK, 0)
          at support/filetools.cpp, during startup. (I believe that fd
          here points at a file on the NFS share.) I can successfully
          start LyX via:
        lyx -userdir ~/tmp/lyx
    say. I can then restart LyX
          with the same command and all is well. I can also start it
          with
        lyx -userdir
          ~/files/lyxnew/
    where that is a
          *non-existent* directory on the NFS share. In that case, LyX
          goes through its configuration process and starts normally.
          However, if I then attempt to run that same command again, LyX
          does not start. Also, if ~/files/lyxnew/
              does exist, then LyX will not start, even if it is empty.
              

    I am seeing a similar
          problem with Libre Office. I can starti fine, but if I then
          attempt to open a file from ~/files/, Libre Office freezes. It
          does not matter when it is ODT or ODS, say. I have not seen
          the problem in other programs, but I only upgraded yesterday.
    I am guessing that there is
          something wrong with the NFS configuration. But I did not
          change anything myself.
