This looks delectable for the eMMC storage alone. I wish there were a Raspberry Pi model that came with it... I'm tired of SD cards causing problems and eating my data or (more frequently) causing the Pi not to boot.

I also wish Raspbian had an option to mount all the write-heavy directories (logs, etc) on tmpfs, so they wouldn't wear the card out so quickly.

Explanations: The script creates a /var/log mount point in RAM. So any writing of the log to the /var/log folder will not actually be written to disk (in this case to the sd card for a raspberry card) but directly to RAM. By default, every hour, the CRON will launch a synchronization of the RAM to the folder located on the physical disk. The script will also make this copy of RAM to disk in case of machine shutdown (but cannot do it in case of power failure). This way you avoid excessive writing on the SD card.
