| /* fstab has the following format: |
| * |
| * Any line starting with a # is a comment and ignored |
| * |
| * Any blank line is ignored |
| * |
| * All other lines must be in this format: |
| * <source> <mount_point> <fs_type> <mount_flags> <fs_options> <fs_mgr_options> |
| * |
| * <mount_flags> is a comma separated list of flags that can be passed to the |
| * mount command. The list includes noatime, nosuid, nodev, nodiratime, |
| * ro, rw, remount, defaults. |
| * |
| * <fs_options> is a comma separated list of options accepted by the filesystem being |
| * mounted. It is passed directly to mount without being parsed |
| * |
| * <fs_mgr_options> is a comma separated list of flags that control the operation of |
| * the fs_mgr program. The list includes "wait", which will wait till |
| * the <source> file exists, and "check", which requests that the fs_mgr |
| * run an fscheck program on the <source> before mounting the filesystem. |
| * If check is specifed on a read-only filesystem, it is ignored. |
| * Also, "encryptable" means that filesystem can be encrypted. |
| * The "encryptable" flag _MUST_ be followed by a = and a string which |
| * is the location of the encryption keys. It can either be a path |
| * to a file or partition which contains the keys, or the word "footer" |
| * which means the keys are in the last 16 Kbytes of the partition |
| * containing the filesystem. |
| * |
| * When the fs_mgr is requested to mount all filesystems, it will first mount all the |
| * filesystems that do _NOT_ specify check (including filesystems that are read-only and |
| * specify check, because check is ignored in that case) and then it will check and mount |
| * filesystem marked with check. |
