increase SD card lifetime

[umiddelb]

Hi,

I'd suggest to add some settings for the image generation procedure which will help to increase the SD card lifetime:

• create the ext4 filesystem without the journal, e.g:

mkfs.ext4 -O ^has_journal -b 4096 -U 9d5de372-3a98-4c65-a236-40d7912153b4 ...

• add / to /etc/fstab like

UUID=9d5de372-3a98-4c65-a236-40d7912153b4  /  ext4  errors=remount-ro,noatime,nodiratime  0  1

nodiratime is already "contained" in noatime source:https://lwn.net/Articles/245002/
