Then again… it appears to work when run as root. It shouldn’t be necessary, at least when run from docker, since CHOWN rights can be granted to the container. Its also going to throw people for a loop constantly (who have a multi-user environment) because the image maintainer (for example, linuxserver) shows PUID/PGID as 1000 in their example. Most people are going to think (rather correctly) that running as root is dangerous.
Anyway, its BETA so what can I expect, right? And there are a lot of open issues so I’m not going to add to the pile. I’ve found a suitable workaround. Eventually though, you’re going to want to consider permission and ownership issues a little more carefully.
