I don't like to use LVM unless there is a compelling reason. It adds additional complexity to managing your filesystems. Also there is greater risk of problems when you use it (eg: 1 drive starts having problems, so your entire lvm becomes unusable until you fix the problem). The only time I've used LVM was on work servers where they originally had 1 mount per drive, so the network shares needed to be moved/trimmed/etc around whenever one of the partitions filled up. I'm sure if you use LVM a lot, then it becomes second nature, and you end up using it everywhere due to the extra flexibility you get (analogy: using git instead of a centralized SCM tool). But for noobs who barely know how to work with it (me), it's easier to just use the default filesystem :-) Beats having to refer to the manual each time you need to fix/check something that I already know how to do without LVM. > I would call my home computer extremely critical.

Are there benchmarks/anecdotal evidence which show how much more reliable a separate root partition is? I would have thought that you'd only separate root part off would be: - You like to use LVM a lot - You have a traditional unix-like filesystem setup, with a lot of root dirs on separate partitions/nfs shares - You use unstable filesystems In the rare event that root part does have a serious error (maybe hardware/power failure/etc): - ext3 (and ext2?) does make backup copies of the superblock. - For all but the most serious problems you should be able to recover by booting from another medium (cd,other hdd, etc) and running fsck/grub/etc - Hopefully you do have good backups in the event that something catastrophic happens to the harddrive (if it does, your other partitions will probably be killed at the same time).
