ctdb-scripts: Avoid ShellCheck warning SC2164 SC2164 (warning): Use 'cd ... || exit' or 'cd ... || return' in case cd fails. A problem can only occur if /etc/ctdb/ or an important subdirectory is removed, which means the script itself would not be found. Use && to silence ShellCheck.

ctdb-scripts: Use load_script_options() in miscellaneous scripts Some of these just aim to load the generic script.options file while others target more specific files. For NFS configuration, always use 60.nfs.options - even for 06.nfs. This could be carefully documented but will change a lot before release so there is no need.
