SD Card corruption?

Anyway, you can run Moode with overlayfs. The downside is, that all history and configuration changes are forgotten at restart.


That 5s write cycle is controlled by an ext4 mount option. From the man page

Quote:      commit=nrsec
              Start a journal commit every nrsec seconds.  The default
              value is 5 seconds.  Zero means default.

As shipped, moOde does not define a value for this option, so it defaults to 5s, but certainly one could experiment with setting it explicitly to, say, 30s, as a way of greatly reducing the number of cycles without totally giving up on the concept.

I wouldn't bother but to each his or her own.

Kent
