[Bug 1871821] Re: [FFe] Resilient boot

** Description changed:

  We're adding support for resilient boot, by modifying grub-install to
  teach it about other ESPs we're installing to, and wrapping it in a
  wrapper script that installs over all ESPs.
  
  This way you can install grub to multiple ESPs which allows you to have
  one ESP per disk in a raid system, for example.
+ 
+ I have extensively tested the grub2 package on amd64, with one, two, and
+ three ESPs. I have not done any testing of the signed package, because I
+ do not have infra around to sign grub and trust it.
