I currently have Redmine setup in /usr/share/redmine and I would like to keep /usr read only. I want to be able to run the application out of /srv/redmine. I am using the debian package. The location where the redmine source is located, /usr/share/redmine, must be mounted readonly. I am looking for a way to run it from /srv if possible with chroot but it does not have to be. This is on a debian system. Can anyone provide me with some guidance about how to do this?
