That's why I use it. Full disk encryption is a good thing. (Well, /boot
is still in the clear, so not quite full.)
I view LVM as yet another layer
of abstraction and yet another way to lose your data.
Agreed.
The most intriguing btrfs, zfs, etc., feature that I have never played
with is the ability to do snapshots. But that is also a scary feature,
allowing me to have parallel universes, each complete in itself? And
what happens when I get confused (or for some other reason) start making
changes in more than one CoW snapshot? Frightening amount of power. The
only think I would trust myself to use it when doing a backup: a
snapshot is a way to prevent version skew while making the backup. But
I'm not running a busy server, a little skew as spam comes into my
laptop isn't going to kill me. I'll risk it for the simplicity.
I use just plain ext4, and "grow" my partitions by using bind mounts.
I use ext4 instead of ZFS for exactly the reason you state: I'm not
willing to make the mental and temporal investment.
I think I started using XFS back when ext2 was still the latest and
greatest of that series and XFS seemed safer, and XFS has been ignorably
reliable ever since, so I keep using it.
