* CUPS: use /etc/cups rather than ${cups}/etc/cups as the ServerRoot,   because CUPS modifies files in the ServerRoot directory.  Most   importantly, it stores printer configuration there.  Previously the   CUPS server modified the files under ${cups}/etc/cups, which is   impure and caused all configured printers to disappear any time CUPS   was upgraded.
