[Bug 1876974] Re: Support multiple ESPs

[Ryan Harper]

What commands are you running and what do you expect to happen that does
not?


If you've installed via subiquity then you can use:

/usr/lib/grub/grub-multi-install

which is what it used during the install to mount and mirror the primary
esp to secondary devices.

Title:
  Support multiple ESPs

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Subiquity has the brilliant feature of supporting installing to
  multiple ESP's. See https://bugs.launchpad.net/subiquity/+bug/1817066
  for details.

  grub-install does not mirror this feature this out of the box, but
  updates the ESP on /boot/efi only by default on such an installation.
  Whenever efi potentially changes, this leaves the backup ESP without
  the update.

  Adding this support would be coherent, since an admin may logically
  assume the install mode is supported beyond the installation phase.
