@bigcalm It's a good filesystem, but, assuming you're using Linux, do you really want to be booting from something that isn't included with the mainline kernel? You might end up having to reinstall if your distro decides it's too much hassle to continue supporting.
@mavit it was something I hear people rave about, but have not used myself. And the Ubuntu installer have it as an option. Shame about the incompatible licences keeping it out of the kernel.
Think I'll stick to LVM and luks.
