Doesn't really help as there is not guarentee important metadata is modified again before the bootloader accesses it, but that's a fate share with any other kind of super sync. The only way to really fix the problem is to implement proper (in-memory) log recovery in the bootloader, especially as it doesn't only have to deal with the relatively easy case of clean shutdowns but also needs to deal with the case of an unclean shutdown with major amounts of updates to the lookup and allocation data structures in the log. IMHO the best option is to have a separate partition for /boot with a very simple filesystem that we can expect boot loader developers to implement fully and correctly. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
