Note that, when testing #30974 on my machine, it caused severe file
system corruption and I had to reinstall.  So I recommend taking a full
backup before trying this on real hardware!

That said, I have tested a more recent version of that patch (attached)
in a VM and it appears to works fine.  Did not get around to trying it
on an already encrypted disk yet though.
