I wanted to point out to you and to @fullzero an issue with the 19-1.3 image that I have noticed others reference here but has not been stated explicitly. The image is actually missing the 0.5.1 DSTM miner that is launched in 19-1.3 3main:

   HCD='/home/m1/zec/zm/5_1/zm_miner'

If you use 4update to get to 19-1.3 there is no issue but if you start with the image provided, the zec miner updates are missing. I noticed this in the version that I downloaded about a week ago so if the image has been updated since then, please disregard.
