title: gitosis: same user multiple machines
body: <p>In git/gitosis a single ssh key is stored with the filename the same as user name.</p>
  
  <p>i.e. myusername.pub</p>
  
  <p>If I want to access a repository from many machines, must I make a new user from each location or is there a way to have multiple ssh keys for a single user.</p>
