If you are using non-journalled file systems on CFdisk, SD or USB then your
shutdown sequence should umount the relevant filesystems to prevent an fsck
on reboot, even if you have done the revevant sync's. If any filesystem is
"busy" (i.e. a daemon with files open on it etc) then umount may be
problematic - umount -r might help. The root filesystem if e.g. ext2 on a
cfdisk, would also be needed to be remounted readonly.
