40 | * Read the config file | |
41 | * | |
42 | * conf_get_uuids gets a list of devicename+uuid pairs | |
43 | * conf_get_devs gets device names after expanding wildcards | |
44 | * | |
45 | * Each keeps the returned list and frees it when asked to make | |
46 | * a new list. | |
47 | * | |
82b27616 NB |
48 | * The format of the config file needs to be fairly extensible. |
49 | * Now, arrays only have names and uuids and devices merely are. | |
50 | * But later arrays might want names, and devices might want superblock | |
51 | * versions, and who knows what else. | |
52 | * I like free format, abhore backslash line continuation, adore | |
53 | * indentation for structure and am ok about # comments. | |
54 | * | |
55 | * So, each line that isn't blank or a #comment must either start | |
56 | * with a key word, and not be indented, or must start with a | |
57 | * non-key-word and must be indented. | |
58 | * | |
59 | * Keywords are DEVICE and ARRAY | |
60 | * DEV{ICE} introduces some devices that might contain raid components. | |
61 | * e.g. | |
62 | * DEV style=0 /dev/sda* /dev/hd* | |
63 | * DEV style=1 /dev/sd[b-f]* | |
64 | * ARR{AY} describes an array giving md device and attributes like uuid=whatever | |
65 | * e.g. | |
66 | * ARRAY /dev/md0 uuid=whatever name=something | |
67 | * Spaces separate words on each line. Quoting, with "" or '' protects them, | |
68 | * but may not wrap over lines | |
