| 47 | * <source> <mount_point> <fs_type> <mount_flags> <fs_options> <fs_mgr_options> |
| 48 | * |
| 49 | * <mount_flags> is a comma separated list of flags that can be passed to the |
| 50 | * mount command. The list includes noatime, nosuid, nodev, nodiratime, |
| 51 | * ro, rw, remount, defaults. |
| 52 | * |
| 53 | * <fs_options> is a comma separated list of options accepted by the filesystem being |
| 54 | * mounted. It is passed directly to mount without being parsed |
| 55 | * |
| 56 | * <fs_mgr_options> is a comma separated list of flags that control the operation of |
| 57 | * the fs_mgr program. The list includes "wait", which will wait till |
| 58 | * the <source> file exists, and "check", which requests that the fs_mgr |
| 59 | * run an fscheck program on the <source> before mounting the filesystem. |
| 60 | * If check is specifed on a read-only filesystem, it is ignored. |
| 61 | * Also, "encryptable" means that filesystem can be encrypted. |
| 62 | * The "encryptable" flag _MUST_ be followed by a : and a string which |
| 63 | * is the location of the encryption keys. I can either be a path |
| 64 | * to a file or partition which contains the keys, or the word "footer" |
| 65 | * which means the keys are in the last 16 Kbytes of the partition |
| 66 | * containing the filesystem. |
| 67 | * |
| 68 | * When the fs_mgr is requested to mount all filesystems, it will first mount all the |
| 69 | * filesystems that do _NOT_ specify check (including filesystems that are read-only and |
| 70 | * specify check, because check is ignored in that case) and then it will check and mount |
| 71 | * filesystem marked with check. |
