Hi!

During the summit, we've discussed several different approaches on how
to solve our issues related to memory erasing.

To report on the "using GRUB" front, there is now a patch that adds a
command to GRUB than should wipe all the available memory, even when
there is more than 4G.

For the patch and some details, please see:
<https://tails.boum.org/bugs/sdmem_does_not_clear_all_memory/grub/>

I have not tested it on bare metal, only qemu and bochs.

The next step is to create a proper "standalone" GRUB image that can be
booted using kexec(). For reasons I don't yet understand, I have not
been able to do so.
