Raw Blame History

Overview

http://ostree.gnome.org is the sole build/deploy server right now.

Notably http://ostree.gnome.org/repo is an OSTree repo which holds binaries.

To install, right now you need to build the 'ostree' git module somehow. I personally use jhbuild, but you could make an RPM/.deb or whatever too.

Replace ~/src with whereever you keep source code.

$ cd ~/src $ git clone git://git.gnome.org/ostree $ cd ostree jhbuild buildone -nf(basename $(pwd))

Now we need to run the install script as root.

$ su -

~/src/ostree/gnomeos/yocto/gnomeos-install.sh

Now you may need to edit your GRUB configuration. This part varies for GRUB 1 versus GRUB 2. The GRUB 2 bits in "15_ostree" don't really work yet. I'm just manually writing GRUB 1 entries.

Running

Once you have a GRUB entry set up, just reboot. Log in as root, there's no password.

One of the first things you'll need to do is add a user. The userid must match the one from your "host" distribution, since we share /home. For example, let's say my login "walters" has uid/gid 500. You should run:

$ groupadd -g 500 walters $ useradd -u 500 -g 500 walters $ passwd walters

Finally, you can start gdm:

$ /usr/sbin/gdm

Updating

You need to pull the latest updates to your repos (assuming that you have your repos in /ostree)

$ ostree-pull --repo=/ostree/repo origin gnomeos-3.4-i686-runtime $ ostree-pull --repo=/ostree/repo origin gnomeos-3.4-i686-devel

And then you need to update your branches: to point to the new stuff. That is a little cumbersome, and the easiest is to use the gnomeos-update-branches script that comes with ostree. The script currently assumes that the repository is in the current directory.
