[How to do instruction] Making your Pi Read-Only

[TheOldPresbyope]

Speaking not as a performer but as the former tech director for 4 years of my grandkids' high school theater productions, there's nothing like a live performance to find out how likely some "extremely rare" thing could happen.  Murphy seems to love an audience.

"Hope for the best but plan for the worst" was our motto.

"Hope for the best but plan for the worst and carry a big stick" was my mentors phrase... (also known as 'percussive maintenance' )

Especially for inanimate contrary mechanical devices. 
This is my favourite applied instance ever...(you will know it well Kent)
