When I take a picture on my phone, #syncthing puts it on the network storage where #inotify sees it and signals #incrond to run 'index' for #photoprism

in other words:

in less then ten seconds every picture taken with my phone is available in my photo-library application and backed up, all using free and open source software.

Why I got Failed to allocate directory watch: Too many open files? #apt #kernel #updates #systemsettings #inotify

Need help with inotifywait loop only processing one file #scripts #inotify

It feels like most smaller cloud providers now tend to offer fast SSD / NVMe #storage only. I need a VM with a small SSD boot disk but a larger disk attached that can be slow. I need to be able to watch file changes via #inotify. Any recommendations? 

Man, using #inotify via the libc calls is a trip.

I just want to block until this one file appears. Is that too much to ask?
