good points thanks - not care much hacking or using unverified module in production - hardening or using reverse fixes that IF opening to public/limited friends on demand via onion
1. NO REASON use dropbox / google / onedrive - whole reason avoiding them their free snooping offers.
2.  Federated  chain delegation thing is new to me - so long link such server  keep all private seems ok
3. At account admin level there are enough security - which group - OTP - folder permission etc 
even sharing via clearnet or onion SOME movies/pics
so far i notice in docker its pretty fast even after REDUCING   CPU threads of NGINX
