To minimize unnecessary writes to UBIFS, does it make sense to mount
with the noatime and nodiratime flags? Some information I've read
suggests that this helps minimize writes and is beneficial to
flash-based filesystems. Is there any downside to using these flags?
Thanks,
twebb

UBIFS does not support atime anyway:

Thanks. Sorry, I hadn't seen that specific question.
Does that mean UBIFS also doesn't support 'diratime'?

Sorry to ask again, but does no "atime" support mean no "diratime"
either for UBIFS?
