Disabling the Ramdisk
mv /var /var_rd
mv /var_orig /var
chmod a-x /etc/init.d/setup_ramdisk
That still leaves the ramdisk_size kernel parameter in the GRUB configuration, but since we've disabled the ramdisk creation script that memory won't be consumed, so we're OK. Might as well leave it as-is, it's one less thing to re-enable when the time comes.
