Package: flash-kernel Version: 3.79 Severity: critical Tags: d-i Justification: breaks the whole system
Dear Maintainer, I used debian installer to install debian on an Allwinner A20-OLinuXino-Lime2 following the instructions at: https://wiki.debian.org/InstallingDebianOn/Allwinner In the debian installer, I changed priority to medium so that I could have control over the partitioning steps. I have an attached SATA disk and partitioned this as physical volume for encryption with a btrfs filesystem on it. I then proceeded to manually create subvolumes on the btrfs filesystem and mounted the root subvolume as /target. Essentially, my /target was mounted as: # mount -t btrfs -o rw,ssd,noatime,nodiratime,compress=lzo,space_cache,subvol=@ /dev/mapper/sda3_crypt /target (Also fixed /etc/fstab) After finishing the install and rebooting, the system fails to boot and u-boot drops into an initramfs shell. The problem is that u-boot does not pass the rootflags=subvol=@ to the boot command. The root btrfs filesystem is mounted on /root in the initramfs rather than the subvolume @ being mounted as /root. I was able to manually remount the subvolume @ onto /root and further mount /boot (which is ext2 filesystem on micro SD card partition 1). I looked in /boot/boot.scr and saw this line: setenv bootargs ${bootargs} quiet which assumes that bootargs may have already been set. I rebooted the system and stopped u-boot to enter the u-boot shell. I added some environment variables as follows: => setenv rootflags 'subvol=@' => setenv bootargs rootflags=${rootflags} => saveenv => reset Now u-boot passes bootargs=rootflags=subvol=@ And the system boot properly. Furthermore, if I run flash-kernel my settings are not overwritten and the system continues to boot properly. However, I don't think this is the correct way to fix the problem. I couldn't see any configuration file for flash-kernel or initramfs-tools for setting rootflags. Is there a configuration option which will add rootflags somewhere so that flash-kernel puts this in the boot.scr file? -- System Information: Debian Release: 9.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: armhf (armv7l) Kernel: Linux 4.9.0-4-armmp-lpae (SMP w/2 CPU cores) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8), LANGUAGE=en_AU:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages flash-kernel depends on: ii debconf [debconf-2.0] 1.5.61 ii devio 1.2-1.2+b1 ii initramfs-tools 0.130 ii linux-base 4.5 ii mtd-utils 1:2.0.0-1 ii ucf 3.0036 Versions of packages flash-kernel recommends: ii u-boot-tools 2016.11+dfsg1-4 flash-kernel suggests no packages. -- debconf information: * flash-kernel/linux_cmdline: quiet
