I set up an central repository in my home directory.
I set it up in my home directory and would like to move it from /home/$USER to /home/share/.
For reference, here are the details of the initial setup for reference following the directions in the bzr documentation:
#establish the central repository
mkdir project
mkdir project/dev
bzr init-repo --no-trees sftp://server/home/$USER/project
bzr init sftp://server/home/$USER/project/trunk
#make local repository
bzr init-repo project
cd project
bzr branch sftp://server/home/$USER/project/trunk dev
#copy files, add to bzr, commit
mv files project/dev/
bzr add
bzr commit -m 'initial import'
