Hi, I went a different route - I purchased a hardened SD-card with static wear levelling built-in.
That way I get a robust system and I do not have to meddle with all this ram based file system trickery.
It is a nice and easy alternative to those, who do not wish to get in with the command line.
Swissbit S-46u 8GB MicroSD
I got mine from Digikey.
@ghydda What is the price of this card?
I payed round about 32 EUR plus sales tax plus shipping.
I see it is currently priced at 35.23 EUR, and that there is 0 in stock:
Digi-Key item no 1052-1262-ND
Mouser also carries SD-cards form Swissbit and so does Farnell
Panasonic also makes some SD-cards with the similar features:
