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
69 *
