So later yesterday afternoon I created a new snapshot with no obvious 
change is free space.

I then update/upgrade.   The initial attempt told me
63 upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
Need to get 337 MB of archives.
After this operation, 473 MB of additional disk space will be used.
Do you want to continue? [Y/n]

But the 3 kernel related packages failed to install a couple of times. 
When I finally figured I should check space, there was none.   I rolled 
back to prior to the upgrade, but still no free space.

I said sometime in this thread that timeshift (and BiT) use hard links 
to create progressive copies of the system. The more I think about how 
hard links reportedly work, I reckon it can't be simply hard links.

So I'm starting a new thread on that topic.
