Re: [Users] Pxeboot

Mike, I 'd like to start again clean. Will the following give me the latest stateless source and iso build: git clone http://gerrit.ovirt.org/p/ovirt-node.git cd ovirt-node

git fetch http://gerrit.ovirt.org/p/ovirt-node refs/changes/38/1738/1 && git cherry-pick FETCH_HEAD

git fetch http://gerrit.ovirt.org/p/ovirt-node refs/changes/38/1738/2 && git checkout FETCH_HEAD
