35 * Read the config file
37 * conf_get_uuids gets a list of devicename+uuid pairs
38 * conf_get_devs gets device names after expanding wildcards
40 * Each keeps the returned list and frees it when asked to make
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.
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.
54 * Keywords are DEVICE and ARRAY ... and several others.
55 * DEV{ICE} introduces some devices that might contain raid components.
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
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
