Thanks, I realized that later (I just cded into the dir and built it). I got some errors after downloading the image, however. I assume it's because I'm on the 3.5 kernel rather than 3.8.

What kind of errors? On kernel < 3.8 docker will print a warning because of a known kernel bug. You may or may not hit the bug on 3.5 depending on your hardware configuration. If you do, you'll know: the kernel will panic ;)

Oh, it wasn't a kernel panic, thankfully :) I closed the window now, but, after downloading the image, I got some errors like "improper file permissions" and "bsdtar exiting".

Sorry I can't provide the exact errors, but if I run it it has to download the entire thing again.

Is there ever a chance to not require aufs? I'd like to use docker on Fedora and maybe even CentOS for fun (managing various containers for some open sauce stuff I maintain), but would prefer to do it without needing aufs.

You guys have fixed every single frustration or oddity I experienced when playing with docker just a week or two ago: * localhost access. * re-attaching to terminal. * set your own port. Brilliant work guys!

Thanks :) Make sure to +1 requests that you want to see next, so we can prioritize accordingly!

Just did on the REST API suggestion! I noticed you mentioned a half-baked proof of concept, if you decide to publish the branch I wouldn't mind hacking on it. :-)

So, what is Docker and why should we care about a 0.x release? Yes, I looked at the link and no, I was not much the wiser, something to do with virtualization perhaps?

It looks to be similar to freeBSD jails

Actually, Docker is like a manager of FreeBSD jails :-) LXC is like FreeBSD jailing.

You mean like this? https://github.com/dotcloud/docker/pull/432

We're seriously looking into btrfs/zfs/qcow etc. Not 100% sure how to get multi-layered mounts and easy export of changes as tarballs.. Hard to beat aufs on those fronts. But we need to make it easier to install on redhat-land, one way or the other.

I encourage you to +1 the relevant issues so we can prioritize!

Correct! In fact there is interest in porting docker to freebsd jails. Ping me if you're interested!

Are you using btrfs, by any chance? Docker currently doesn't support it: https://github.com/dotcloud/docker/issues/339
