From Fedora Project Wiki
Download the latest root filesystem tarball from http://ftp.linux.org.uk/pub/linux/arm/fedora/rootfs/ and untar it.
This assumes that you untarred the root file system in /mnt/ARM_FS. We need to export it through NFS. Add the following in your /etc/exports.
/mnt/ARM_FS/ *(rw,sync,no_root_squash)
Now, restart the NFS service.
/sbin/service nfs restart
