So here I am again, it was quiet for some time but I had a look again at my block stats and something is writing to mmcblk0p1 every 10 minutes
Assuming it is always the same file and knowing how bad eMMC wear-leveling can be, this is not a good thing.
The file to blame is
/.wget-hsts which is used to track HSTS for wget… the issuer of the wget calls is dyndns… and
api.turris.cz also is included… but I would assume when the ip check on dyndns uses HSTS this file will be touched every 10 minutes…
I created a
hsts=0 in it and hope this will prevent wget from using the file every time.
This seems to work for me…
