    <div>While these things are annoying, I'd be
      happy(er) if the latest "upgrade" or two didn't break basic
      functionality:</div>
    <div><br>
    </div>
    <div>1.  Clicking on a link in a Thunderbird
      email usually doesn't open the link.</div>
    <div>2.  Clicking on a window doesn't bring
      it to the foreground anymore.  I have to click on the desired
      program in the left vertical panel instead.</div>
    <div>3.  Doing "save as" frequently, perhaps
      always, doesn't work properly anymore.  I  have to use "print to
      file" as a workaround.</div>
    <div><br>
    </div>
    <div>But I don't get Brian's weird df
      output, it's the same as it's always been, for me.</div>
    <div><br>
    </div>
    <div>I'd migrate elsewhere, but I do
      business on this machine, and that scares me.</div>

        <div>Seriously, Ubuntu keeps putting more and more things in

        <div>If every major package was in a snap there would be

        <div>Why would anyone think this is a good idea?<br>
          <br>

        <div>And who would design a modern packaging system that makes
          you stop running the app before it can be upgraded?  Imagine
          what it would be like once there are hundreds of snaps
          installed!<br>
        </div>
        <div>All of them tell you to exit the app for upgrade.  At least
          Windows and MacOS only make me reboot.<br>
        </div>
        <div><br>
        </div>
        <div>Look carefully at the "disk free" output... not one of them
          is an actual disk device.<br>

        <div>This is worse than systemd (which is responsible for
