/* 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.
