Well technically they could start with the GRUB zfs code, which is

As explained in depth in a previous posting, there is absolutely no

You are sadly mistaken.
From GNU.org on license compatibilities:
http://www.gnu.org/licenses/license-list.html
What you read there is completely wrong :-(
The FSF even knows that it is wrong as the FSF did never sue Veritas
for publishing a modified version of GNU tar that links against
close source libs from veritas.
The best you can do is to ignore it and to ask independent lawyers.
I encourage you to read my other post that in depth explains why the
FSF
publishes incorrect claims.
There was nothing there other than fluff from a different website,
though. And your argument "Look, it says it's Open Source here" means
that they are compatible is not the generally held position of almost
everyone else who has looked into this.
The GPL doesn't prevent you doing things. However, it does withdraw
the agreement that you are permitted to copy someone else's work if
you do those things. So whilst one can compile and link code together,
you may not have the rights to use other's code without every
committers individual agreement that you can copy their code.
The GPL doesn't prevent; it just withdraws rights - without which, you
may be breaking copyright. And the GPL has been tested a number of
times in court with regards to copyright violations where the GPL no
longer covers you to do the same.
As an observation, the Eclipse Foundation lawyers have agreed that the
GPL is incompatible with the EPL for the same reasons:
