Minimizing writes to SD card - reducing wear

Hi,

I’m wondering if anyone has experience w/ maintaining Ubuntu Core based devices that use an SD card for storage.

Are there any mechanisms in UC to help limit filesystem writes (i.e. noatime, keeping logs in memory based overlay, etc…) that are part of the system or can otherwise be configured?

Thanks a bunch,
Jesse

noatime is a default mount option in Ubuntu Core and logs are by default in ram (journald only logs to disk if you manually create /var/log/journal)

i have a bunch of Pi’s around that use the same SD card since the initial core 15.04 and have been re-flashed regulary without showing any wear levelling issues yet … if your application snaps dont do any excessive writing you should be fine for several years with Ubuntu core 18 i a default setup.

Thanks, that’s the confirmation I was looking for.
