[Bug 1396379] Re: installer uses first EFI system partition found even when directed otherwise

[Tim Richardson]

I'm not downplaying the severity, I am being accurate about it. Bugs are
given severity ratings so that good priority decisions are made. I can't
fix this bug in any practical way, but the least we can do is keep the bug
report accurate.
It is an annoying and bad user experience for a fairly niche instance. That
is bad. But this bug does not cause actual data loss, and we should not say
that it does when it doesn't. I don't think falsely inflating the severity
of bugs to try to get attention is healthy, although I agree it is
tempting. So now you know my motivation for intervening with this
non-technical content. No more such discussion from me, you either agree or
not about that opinion, and you apparently already agree with my technical
assessment.

Title:
  installer uses first EFI system partition found even when directed
  otherwise

Status in grub-efi-amd64-signed package in Ubuntu:
  Confirmed
Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  (k)ubuntu 14.04.1
  package version: 2.02~beta2-9ubuntu1

  i installed ubuntu on my external hard disk, where i also have a previously installed fedora system. i also have a windows
  (efi-booted) system in the internal hard disk.

  at install time via ubiquity i get all grub configuration files in the first EFI-labelled partition (i.e. /dev/sda2 in my case) instead of the one i selected (/dev/sdb1).
  later i changed my fstab mounting /boot/efi on /dev/sdb1 and tried to reinstall grub package (apt-get install --reinstall grub-efi-amd64); now all grub configuration files are in the rigt place, but booting from the external hard disk still shows the fedora grub installation, while selectin the internal hard disk from the bios menu shows a submenu listing ubuntu and windows.
  explicitly installing grub in the correct disk (grub-install /dev/sdb; grub-mkconfig -o /boot/efi/EFI/ubuntu/grub.cfg) has no effect, nor it has running efibootmgr (efibootmgr -c --disk /dev/sdb --part 1).

  expected results: grub shoud have been installed in the disk/partition i chose;
  actual results: ubuntu always chooses the first disk to install grub on.

  Note that this is not just about the dummy grub install location
  selector that is not used in EFI mode, but configuring one partition
  as do not use, and the other as ESP in the manual partitioning screen.
