35 | * Read the config file | |
36 | * | |
37 | * conf_get_uuids gets a list of devicename+uuid pairs | |
38 | * conf_get_devs gets device names after expanding wildcards | |
39 | * | |
40 | * Each keeps the returned list and frees it when asked to make | |
41 | * a new list. | |
42 | * | |
82b27616 NB |
43 | * The format of the config file needs to be fairly extensible. |
44 | * Now, arrays only have names and uuids and devices merely are. | |
45 | * But later arrays might want names, and devices might want superblock | |
46 | * versions, and who knows what else. | |
47 | * I like free format, abhore backslash line continuation, adore | |
48 | * indentation for structure and am ok about # comments. | |
49 | * | |
50 | * So, each line that isn't blank or a #comment must either start | |
51 | * with a key word, and not be indented, or must start with a | |
52 | * non-key-word and must be indented. | |
53 | * | |
31015d57 | 54 | * Keywords are DEVICE and ARRAY ... and several others. |
82b27616 NB |
55 | * DEV{ICE} introduces some devices that might contain raid components. |
56 | * e.g. | |
57 | * DEV style=0 /dev/sda* /dev/hd* | |
58 | * DEV style=1 /dev/sd[b-f]* | |
59 | * ARR{AY} describes an array giving md device and attributes like uuid=whatever | |
60 | * e.g. | |
61 | * ARRAY /dev/md0 uuid=whatever name=something | |
62 | * Spaces separate words on each line. Quoting, with "" or '' protects them, | |
63 | * but may not wrap over lines | |
64 | * | |
