Package: grub2-common Version: 2.02+dfsg1-20+deb10u4 Severity: important Dear Maintainer,
Upgrading to grub 2.02+dfsg1-20+deb10u4 caused grub-install --target=x86_64-efi to be executed. It failed (as expected) so I ran grub-install --bootloader-id=debian1buster --efi-directory=/boot/efi1 /dev/sda grub-install --bootloader-id=debian2buster --efi-directory=/boot/efi2 /dev/sdb because I'm running two drives under software RAID1 and I wanted boot redundancy. In order to get there I have two entries in the EFI as (sda1)/boot/efi1/EFI/debian1buster and (sdb1)/boot/efi2/EFI/debian2buster giving efibootmgr -v of Boot0000* debian1buster HD(1,GPT,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx,0x800,0x100000)/File(\EFI\debian1buster\shimx64.efi) Boot0002* debian2buster HD(1,GPT,xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx,0x800,0x100000)/File(\EFI\debian2buster\shimx64.efi) Where sda2/sdb2 are the RAID1 set. Upon boot I'd get 'grub>'. Entering 'set' (under 'grub>') showed 'prefix' as '/EFI/debian'. Running grep -l '/EFI/debian' /boot/efi1/EFI/debian1buster/* returned 'grubx64.efi'. Leading me to believe that grub-install is not honoring the --bootloader-id parameter when grubx64.efi is built. My temporary solution was to copy /boot/efi1/EFI/debian1buster to /boot/efi1/EFI/debian and /boot/efi2/EFI/debian2buster to /boot/efi2/EFI/debian and now the system will boot properly. Without knowing the particulars of Grub, it was a little surprising that grub-install sets prefix in the first place; before it read the grub.cfg file in current directory (/boot/efi1/EFI/debian1buster/). I wonder if BOOTX64.CSV should be effected to prevent both of the efi1/efi2 entries to be "shimx64.efi,debian,,This is the boot entry for debian"; such that the ',debian,' should be the --bootloader-id value as well. I also wish that my 'debian1buster' entry would stop getting deleted from EFI. I haven't figured out who to blame yet. -- Package-specific info: *********************** BEGIN /proc/mounts /dev/mapper/vg1bus-lv01 / ext4 rw,relatime,errors=remount-ro 0 0 /dev/mapper/vg1bus-lv09 /usr ext4 rw,relatime 0 0 /dev/sda1 /boot/efi1 vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 0 /dev/sdb1 /boot/efi2 vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 0 /dev/mapper/vg1bus-lv04 /srv ext4 rw,relatime,stripe=4 0 0 /dev/mapper/vg1bus-lv08 /tmp ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv03 /opt ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv10 /var ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv02 /home ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv11 /var/log ext4 rw,relatime,stripe=4 0 0 /dev/mapper/vg1bus-lv07 /var/mail ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv12 /var/spool ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv13 /var/tmp ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv06 /srv/backup ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv15 /srv/tmp ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv14 /srv/vm ext4 rw,relatime 0 0 /dev/mapper/vg1bus-lv05 /srv/docs ext4 rw,relatime 0 0 *********************** END /proc/mounts *********************** BEGIN /boot/grub/device.map (hd0) /dev/disk/by-id/ata-CT500MX500SSD1_xxxxxxxxxxxxx (hd1) /dev/disk/by-id/ata-CT500MX500SSD1_xxxxxxxxxxxxx *********************** END /boot/grub/device.map *********************** BEGIN /proc/mdstat Personalities : [raid1] md127 : active raid1 sda2[0] sdb2[1] 487525376 blocks super 1.2 [2/2] [UU] bitmap: 1/4 pages [4KB], 65536KB chunk unused devices: <none> *********************** END /proc/mdstat -- System Information: Debian Release: 10.8 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-14-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE= (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages grub2-common depends on: ii dpkg 1.19.7 ii grub-common 2.02+dfsg1-20+deb10u4 ii install-info 6.5.0.dfsg.1-4+b1 ii libc6 2.28-10 ii libdevmapper1.02.1 2:1.02.155-3 ii libefiboot1 37-2+deb10u1 ii libefivar1 37-2+deb10u1 ii liblzma5 5.2.4-1 grub2-common recommends no packages. grub2-common suggests no packages. -- no debconf information
