That's a good point, thanks. A dirty hack comes to my mind, back from the days of DOS: files marked = with=20 `system' attribute were not moved during defrag (important for io.sys &= =20 msdos.sys). Perhaps using some sensible attribute (i? t? a new one?) wo= uld=20 prevent nilfs_cleanerd from moving the file? Would require implementing attributes on NILFS, thou.
