[A slightly relevant Windows war story.  Really a whine.  Consider
skipping.]

I've been wrestling with Win10.  It really isn't good doing Windows
Update with a 32G "HDD".

Why should it handle this size?  Because Microsoft forced this size upper
limit on manufacturers with their licensing terms.  I even bought a
few such machines from Microsoft itself.  (They run Linux just fine.)

I recently got stuck with not enough space on C: (think /root).  Even
when I threw everything overboard.  One possible victim was left: the
Paging File.  It was stubbornly stuck at 1.1GiB.  I wanted to put a
paging file on another drive so that I could get back the 1.1G of
space on C:.

The documentation says that this is possible with a USB stick or SD
card iff it was ReadyBoost ready.  That supposedly means "fast
enough".

- ReadyBoost is an obsolete technology.  Vendors don't sell ReadyBoost
  ready devices

- there is a ReadyBoost tab when you look at device properties in
  Win10.  It just tells me that it is disabled on my computer because
  I have an SSD c:.  Not useful.  I want to know about ReadyBoost
  ready, not actually use ReadyBoost.

- the Paging File configuration setting (buried way deep in Win10)
  doesn't see my USB flash sticks or my SD card.

- the Paging File configuration setting does see an external USB HDD.
  So I try that.

  When I reboot, Win10 says that it has to temporarily create the
  Paging File on C:.  So this is no advance.

- Microsoft Support struggle with understanding the issue.  When they
  do, they give useless advice.
