Yes, but there are two reasons I don't use them. One is that the capacity
of your cache is not included in the filesystem - ie with a 250GB SSD and
500GB the filesystem capacity will be 500GB not 750GB.
The second is that I use btrfs for my root filesystem so I'd have to get
bcache/EnhanceIO integrated into the distributor's initramfs build
mechanism, as well as worry about livecd/network boots without it. This
is a lot of unnecessary work and worry.
