Hi Torproject,
i think about enabling AvoidDiskWrites 1 on all my relays and not only on my Pi because the prices for the VPS are anyway cheap as f*ck so i think saving the provider a few disk writes is a nice deal.
In the manual it is described as:
AvoidDiskWrites 0|1
If non-zero, try to write to disk less frequently than we would otherwise.
This is useful when running on flash memory or other media that support
only a limited number of writes. (Default: 0)
... which is not a very informative description on how it changes the behavior of Tor. I didnt found any more explanation about it.
