Comment 6 for bug 252900

Can anyone talk me through these fixes, normally I'd charge ahead and give it a go but I sense that doing that with boot and kernel stuff when I don't really understand exactly what I'm supposed to do is a bad idea.

What is a linux file system and how do I know if any of my drives have one?

Or - if I remove the boot mount point from fstab how do I then unmount boot? And I can't find a folder in host called disks?

Or - how do I remove/purge the old package first and how do I install an older backup?
