sd card writes / lifespan

[DaLiV]

exist periodic writes to
/kvmapp/kvm/now_fps

but as device runs from SD cards, which bad tolerances to re-writes - would be nice to check that all "temporal" writes goes to /tmp systems ... (also as logs, which rarely need to be "live" between restarts)
especially as devices are intended to be used for remote access and any type of fault can lead to need to drive some hundred KMs for replacing SD card.
