{{Note/important|Important notes for XO users:|Some XO images might mount {{Code|/var/cache/yum}} to the tmpfs. With this limited cache capacity, it will be mostly impossible to install anything of large size from the Fedora repositories. To work around this limitation, become a {{Code|root}} user and enter the {{Code|umount /var/cache/yum}} command in the Terminal activity or a console. To persist this change for subsequent boots, remove the corresponding line from the {{Code|/etc/fstab}} file.}}
