Late answer, but for up-to-date info...
If you install node.js using the recommend method from the node github installation readme, it suggests following the instructions on the nodesource blog article, rather than installing from the out of date apt-get repo, node.js should run using the node command, as well as the nodejs command, without having to make a new symlink.
This method from article is:
# Note the new setup script name for Node.js v0.12
curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash -
# Then install with:
sudo apt-get install -y nodejs
Note that this is for v0.12, which will get likely become outdated in the not to distant future.
Also, if you're behind a corporate proxy (like me) you'll want to add the -E option to the sudo command, to preserve the env vars required for the proxy:
curl -sL https://deb.nodesource.com/setup_0.12 | sudo -E bash -
