Certainly, a proper shutdown (exit, exit) should do the trick. A sync
will flush the buffers, and probably exiting chroot will force a sync. I
personally prefer to unmount volumes manually just as a paranoid
precaution. And you certainly would not be permitted to unmount the
volume while in the chroot session.
