[Bug 1060404] Re: update-grub runs and fails in containers
For the record, this hasn't fully been fixed in Quantal: Quantal's /etc/kernel/postinst.d/zz-update-grub does NOT have the container check as introduced in precise's grub2 (1.99-21ubuntu3.9) SRU.

[Bug 1060404] Re: update-grub runs and fails in containers
This bug was fixed in the package grub2 - 2.00-7ubuntu3 --- grub2 (2.00-7ubuntu3) quantal; urgency=low * If the postinst is running in a container, skip grub-install and all its associated questions (LP: #1060404). * Merge UEFI secure boot tweaks from Fedora: - Don't error on insmod on UEFI/SB, but also don't do any insmodding. - Add sleep to the list of modules in the signed image. * Move Ubuntu modifications to the Fedora linuxefi patch into separate patches, to ease maintenance. * Implement secure boot handling policy as outlined by Steve Langasek: - Make the linux module call linuxefi when necessary, simplifying configuration. Add the linux module to the signed image. - If secure boot is enabled and the kernel is signed, linux will call linuxefi to hand over to it without calling ExitBootServices. - Otherwise, linux will fall through to previous code, call ExitBootServices itself, and boot the kernel normally. - Change linuxefi to return GRUB_ERR_ACCESS_DENIED rather than GRUB_ERR_INVALID_COMMAND in the case of an invalid signature, to make it easier to implement different handling of unsigned kernels in future if necessary. * Build two images for signing: one with prefix /EFI/BOOT for use on removable media, and one with prefix /EFI/ubuntu (and with the lvm, mdraid09, and mdraid1x modules added) for use on fixed disks. Setup mostly borrowed from Fedora. * Generate configuration for signed UEFI kernels if available. -- Colin Watson cjwat...@ubuntu.com Sun, 07 Oct 2012 11:36:29 +0100 ** Changed in: grub2 (Ubuntu Quantal) Status: Fix Committed = Fix Released -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1060404 Title: update-grub runs and fails in containers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1060404/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1060404] Re: update-grub runs and fails in containers
** Description changed: - If grub is installed in a container (as happens, for instance, with the - ubuntu-cloud template) then an update of grub or linux-image will cause - update-grub to be run. It tries, finds it can't access the root device, - fails, and causes the update to fail. + == + SRU justification for lxc part: + 1. Impact: update-grub fails, causing apt-get updates to fail if there is a new kernel. + 2. Development fix: modify ubuntu templates to mount devtmpfs before starting container + 3. Stable fix: same as development fix. + 4. Test case: + sudo lxc-create -t ubuntu-cloud -n q1 + sudo lxc-start q1 + # inside the container, run sudo update-grub + 5. Regression potential: This adds one more mount per container (by default, removable), taking up more memory. + == + If grub is installed in a container (as happens, for instance, with the ubuntu-cloud template) then an update of grub or linux-image will cause update-grub to be run. It tries, finds it can't access the root device, fails, and causes the update to fail. It would be better for update-grub to detect that it is in a container and simply exit 0, so that the apt-get can succeed.

[Bug 1060404] Re: update-grub runs and fails in containers
After talking to cjwatson on irc, there is another option. update-grub
is failing because /dev/disk/ is not set up in the container. So we
could add an upstart job which runs only in containers, and manually
sets up /dev/disk/. This also might help other software which relies on
/dev/disk/. However, as grub is not installed in ubuntu containers by
default (but is installed in ubuntu-cloud containers) we can't blindly
re-use grub-probe. If we use grub-probe only if it is available, then
we are helping fewer cases. If we detect the root device by hand, I
fear we are duplicating too much fragile code.
Perhaps the best option is simply an upstart job like the below (but
smarter and safer):
start on starting mountall
task
script
type grub-probe /dev/null 21 || { exit 0; stop; }
mkdir -p /dev/disk/by-label /dev/disk/by-uuid
rootdev=`grub-probe -t device /`
do_mknod /dev/rootdev
rootlabel=`grub-probe -t fs_label /`
ln -s ../../$rootdev /dev/disk/by-label/$rootlabel
rootuuid=`grub-probe -t fs_uuid /`
ln -s ../../$rootdev /dev/disk/by-uuid/$rootuuid
end script

I've pushed a patch to ubuntu:lxc which will cause devtmpfs to be mounted in ubuntu containers. There remains the problem that grub-install then queries the user about installing grub on /dev/vda1 (or whatever is hosting the container fs). ** Changed in: upstart (Ubuntu) Status: New = Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1060404 Title: update-grub runs and fails in containers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1060404/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
