Write doesn't sync to disk so a crash can corrupt data. One example of this is here:

neutrino/headerfs/file.go

Lines 19 to 25 in 4bc2c99

func (h *headerStore) appendRaw(header []byte) error {
if _, err := h.file.Write(header); err != nil {
return err
}
return nil
}

I forget if there are other call-sites
