Again, Roberto, a journaling filesystem is not necessary for /boot. It will not make files in /boot any more crash resistant. Files in /boot are only modified when you replace (upgrade) your kernel. Corruption can only occur when file writes are in flight but not completely on disk. Therefore, to corrupt files in /boot, the machine must crash or lose power while you're installing a new kernel, i.e. within a window of about 10 seconds. There are 31,536,000 seconds in a year. So the odds of a crash/power loss during any one of your kernel upgrades are, if my math is close, approximately 1 in 3,153,600 > If i need a home directory with crypt filesystem, what should i use?

Is this a workstation, personal server, or multiuser server with decent load? If the load is light you can get away with multiple XFS filesystem on a single spindle, separate rootfs and home. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
