I've been postponing the upgrade of the rasPi 1B+ to Stretch for a
while… well, the three year old SD card gave up the ghost while I was
away over the holidays, so that has been forced on me to do yesterday.
After a few days of trying I could actually dump an image of the card so
I have salvaged the logs up until the filesystem went read-only and I
only lost about a week of data (the ntpd itself was still operational).
Here are the notes from my install in the hope it may help somebody on
their next installation:
