Package: grub-common Version: 2.00-18 Severity: normal
Dear Maintainer, I tried to upgrade the EFI version of grub installed in my system using the following command: $ sudo /usr/sbin/grub-install /dev/sdaX (where sdaX is the partition where my root filesystem and grub is installed). My uprgade attempt wasn't completely successful since on reboot I was brought to the grub rescue console. On investigation I found that the problem arose because my EFI partition wasn't mounted. To avoid polluting my system, I had made a separate 1 MB EFI partition that I normally don't mount. I managed to successfully update my EFI grub installation using the following sequence of commands: $ sudo mount /dev/sdaY /boot/efi $ sudo /usr/sbin/grub-install /dev/sdaX (where sdaY is my small EFI partition, and sdaX is my / partition). This is necessary because grub needs to update the following file: /boot/efi/EFI/debian/grubx64.efi (which is not possible if the EFI partition isn't mounted). I'm marking this bug report with normal severity since my setup is most likely a corner case, and most users would probably have their EFI partition permanently mounted (less secure but more convenient). However, I do believe that grub-install should either (1) be fixed to force or allow the mounting of the EFI partition or (2) at least notify or WARN the user that the EFI version of grub requires the EFI parition to be mounted first. A third alternative is to (3) make grub-install fail if a VFAT filesystem is NOT mounted at /boot/efi (inasmuch as EFI is broken in its ability to boot native Linux filesystems). -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (900, 'testing'), (90, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.10-2-amd64 (SMP w/2 CPU cores) Locale: LANG=en_SG.UTF-8, LC_CTYPE=en_SG.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages grub-common depends on: ii gettext-base 0.18.3.1-1 ii libc6 2.17-92 ii libdevmapper1.02.1 2:1.02.77-5 ii libfreetype6 2.4.9-1.1 ii libfuse2 2.9.2-4 ii liblzma5 5.1.1alpha+20120614-2 ii zlib1g 1:1.2.8.dfsg-1 Versions of packages grub-common recommends: ii os-prober 1.63 Versions of packages grub-common suggests: ii console-setup 1.95 ii desktop-base 7.0.3 pn grub-emu <none> pn multiboot-doc <none> ii xorriso 1.2.2-2 -- no debconf information -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
