30/* fstab has the following format:
31 *
32 * Any line starting with a # is a comment and ignored
33 *
34 * Any blank line is ignored
35 *
36 * All other lines must be in this format:
37 * <source> <mount_point> <fs_type> <mount_flags> <fs_options> <fs_mgr_options>
38 *
39 * <mount_flags> is a comma separated list of flags that can be passed to the
40 * mount command. The list includes noatime, nosuid, nodev, nodiratime,
41 * ro, rw, remount, defaults.
42 *
43 * <fs_options> is a comma separated list of options accepted by the filesystem being
44 * mounted. It is passed directly to mount without being parsed
45 *
46 * <fs_mgr_options> is a comma separated list of flags that control the operation of
47 * the fs_mgr program. The list includes "wait", which will wait till
48 * the <source> file exists, and "check", which requests that the fs_mgr
49 * run an fscheck program on the <source> before mounting the filesystem.
50 * If check is specifed on a read-only filesystem, it is ignored.
51 * Also, "encryptable" means that filesystem can be encrypted.
Dees Troy4dff2e62013-11-10 04:11:43 +000052 * The "encryptable" flag _MUST_ be followed by a = and a string which
53 * is the location of the encryption keys. It can either be a path
Dees_Troy51a0e822012-09-05 15:24:24 -040054 * to a file or partition which contains the keys, or the word "footer"
55 * which means the keys are in the last 16 Kbytes of the partition
56 * containing the filesystem.
57 *
58 * When the fs_mgr is requested to mount all filesystems, it will first mount all the
59 * filesystems that do _NOT_ specify check (including filesystems that are read-only and
60 * specify check, because check is ignored in that case) and then it will check and mount
61 * filesystem marked with check.
