Official image is already there, waiting for this PR for a nice page at the Docker Hub.

LGTM

Whoa one sec, just noticed that --privileged. That's going to need some explanation. 😉

There's got to be a way to make the package manager work with less than full --privileged. 😕

CastFS failed the sanity check, staging disabled!

Looks like it does work fine without --privileged, it just doesn't get the full benefit of "CastFS".

(Which I think is more OK in the case of Docker than in the normal desktop case since your installation ought to be happening in throw-away containers anyways, right?)

I successfully got CastFS to work with just --device /dev/fuse --cap-add SYS_ADMIN, which is better than --privileged (which gives full privileges to the entire host device hierarchy, for example), but still isn't great since SYS_ADMIN controls a lot more than just whether we can mount. Since it works without, I think I'd rather we not include it by default, and have CastFS notes in a separate section noting that there are security implications to granting these capabilities/privileges to the container.

This is also really important to note because in a Dockerfile, we have no way of adding devices or extra capabilities, so it's great that the following Dockerfile actually works: (just tested it! 👍)

FROM sourcemage
RUN cast tmux

Got it.

Please see my latest commit which takes care of that.

LGTM

Awesome, thanks! 👍
