What the Linux client (in contrast to the Windows client) does not support is having virtual files in a folder and only downloading files on demand.

This is specifically what I want.

And...somehow I missed opencloud in all of my searching? I think I may have mentally combined it with OwnCloud/OCIS. It looks promising. Diving into the docs, now.

Seafile apparently obfuscates the files, which is not great. If it dies, or they pull some weird shutdown shenanigans, what happens to my files? Nexcloud, at least, is readable and organized, if (in my opinion) weird.

Good call on the cable checking. My initial thought was "well, duh" but then I realized it hadn't occurred to me. So, thank you for that!

I'll probably secure the video cards separately, just because I hate how "loose" they feel when installed correctly and remaining untouched, let alone being moved by forklifts and on a flatbed trailer for over 30 hours.

Can you use the coral in any capacity outside of podman? It's been a while, but I seem to recall similar issues, and using a different cable solved my issues. I specifically remember the cable being problematic, but not what the problem was (I'm pretty sure it wasn't because the first cable was a crappy charge-only thing)

I thought the same thing, but I've spent a good chunk of time looking at every button in the linux client, and it's just options of "sync: y/n", with an initial choice of "do not sync if folder size is 500MB+". And the files/folders not synced do not show up locally. The windows client lets you see everything, but only download when you open or pick "save locally". But not on Linux.

Fair enough. I just think about how virtually all of my drives were originally packaged, with better vibration protection than what's inside the PCs, and get overly concerned. It's a lot of media I don't want to recover if it's lost.
