161 | * Important Note: | |
4110345b | 162 | * If a new config option is added to this table, be aware that |
20c3318a MB |
163 | * the order in which the options are places into the table matters. |
164 | * That means that more specific options of a namespace have to be | |
165 | * placed above more generic ones. | |
166 | * | |
167 | * For instance: If lxc.ab is placed before lxc.ab.c, the config option | |
168 | * lxc.ab.c will always be matched to lxc.ab. That is, the lxc.ab.c option | |
169 | * has to be placed above lxc.ab. | |
