| * Read the config file |
| * |
| * conf_get_uuids gets a list of devicename+uuid pairs |
| * conf_get_devs gets device names after expanding wildcards |
| * |
| * Each keeps the returned list and frees it when asked to make |
| * a new list. |
| * |
| * The format of the config file needs to be fairly extensible. |
| * Now, arrays only have names and uuids and devices merely are. |
| * But later arrays might want names, and devices might want superblock |
| * versions, and who knows what else. |
| * I like free format, abhore backslash line continuation, adore |
| * indentation for structure and am ok about # comments. |
| * |
| * So, each line that isn't blank or a #comment must either start |
| * with a key word, and not be indented, or must start with a |
| * non-key-word and must be indented. |
| * |
| * Keywords are DEVICE and ARRAY |
| * DEV{ICE} introduces some devices that might contain raid components. |
| * e.g. |
| * DEV style=0 /dev/sda* /dev/hd* |
| * DEV style=1 /dev/sd[b-f]* |
| * ARR{AY} describes an array giving md device and attributes like uuid=whatever |
| * e.g. |
| * ARRAY /dev/md0 uuid=whatever name=something |
| * Spaces separate words on each line. Quoting, with "" or '' protects them, |
| * but may not wrap over lines |
