Done and done. I just took a screenshot, ctrl+v’d it right in the same browser tab and then went to my phone and hit reply on this post and attached the image. Its the best desktop -> mobile experience Ive used in a long time. It just works once you get it going. I pass through the igpu of a proxmox host into the VM and aside from some earlier compatibility issues (I think its mostly on my end, GVT-v, i915 and a bungled original grub config) the ML has been crash free for almost a year. Ive had 0 uptime issues (now that i only pull monthly) and I was smart with my initial compose script and everything is external. mountpoints are external, all the storage is over 10g to a truenas box.
I havent done much with it other than get all our paper recipes into it and added some via import. I am looking forward to it as its my next project now that photos are done.
