Is there any guide or docs for union? The official docs are very unclear and are missing a lot of information. No clue what those policies mean. How can I mount a union remote? Can I mount it with systemd just like mergerfs? Can the same options be used like "vfs cache mode" and "buffer size" for example. I don't understand what the cache time does. Just one sentence doesn't cover it. What is path preserving polices?
Any guide or anything to get me started would be greatly appreciated.
I'm not sure why you'd use mergerfs or union for mounting a single item. A union or mergerfs is generally for using more than one remote/mount to combine them based on a policy.
So what are you trying to do is the question? If it is
There's no reason to use union or mergerfs as it's a single remote. Just mount it.
I have been running rclone with mergerfs before so I can write files to a local folder and access the cloud files in the same folder. What approach would you recommend then?
The problem is, Before I mounted the rclone mergerfs on top of a zfs pool with a different linux distro. Now I have 2 ssd's merged with mergerfs and on top of that I would like to mount the rclone mount. If I do that I cannot access my folder with a different user than root.
I am running docker containers like plex with user 1000 and group 100. Just like the rclone mount. But for some reason I can't access the folder from inside plex.
