It’s a bit hacky but I suppose there’s always the option of using a separate WebDAV server on the directory where frappe drive stores its files. I haven’t tried something like that, though. Unfortunately I don’t know of any integration within frappe drive itself. Seems they’re accepting contributions now so it’s possible these will be implemented in the future. WebDAV is a bit of its own beast, though, so that’ll be a huge undertaking in my opinion.
I wouldn’t say I’m in control per se when I don’t have the option to just do the update whenever I feel like it. I’m in control the same way a prisoner is in control of whether or not they eat that day by just not eating. Like, put it behind a giant bold unmissable piece of text that says “IF YOU DO THIS YOU ARE PUTTING YOUR MACHINE AT RISK AND HACKERS WILL IMMEDIATELY STEAL ALL YOUR MONEY” but don’t make it so it’s impossible for me to do without some workaround.
