CentOS is a RedHat-like Linux distro, so you should follow the Fedora instructions. Two additional gotchas may present themselves.

  1. /dev/null is not world-writable. You need to

    chmod 777 /dev/null

    in order for Instiki to be able to function.

  2. /dev/urandom is not a “special character device.” You need to

    rm /dev/urandom
    mknod -m 644 /dev/urandom c 1 9
    chown root:root /dev/urandom

    in order for BZR to function.

In both cases, these need to be placed in a startup script, because rebooting the server will recreate the problem.
