Both functions will be used by rootfs-block and fstab-sys modules.
Both are based on code present in mount-root.sh, though few changes are
present.
det_fs:
will try to determine filesystem type for supplied device, even if it's
not auto. If fs cannot be detected, or if the detected one differs from
the supplied one - a warning is issued (so user can fix its stuff later)
wrap_fsck:
will call fsck for specific device with optionally additional
fsckoptions. The function returns fsck return value.
