SysV init scripts should sync things, but "sync;sync;reboot" or "sync;sync;halt" are not so nice in how they go down; so it's a case of being extra careful. I don't use linux all the time, and some of the other unices are less tolerant. (For example, on a sun box, I would prefer a double sync before I "-a".) -- timothy.covell@ashavan.org. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
