I do it because.. well.. first off, it allows me to have /boot on different raidlevel than / or /home without extra disks. secondly, it allows me to with the same disks use different filesystems.. for instance, it allows me to have /home encrypted with dm-crypt, while still raided.. Not that i would mind encrypting / and /home as 1 partition, but it creates a whole slew of issues with having to create initrd and stuff.. I realize that performance probably suffers abit from this, but well.. is there any stability or security wise risk? i mostly use raid1 and raid5 only.. > > -- > 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/
