Package: grub-common Version: 2.04-4 Severity: normal Dear Maintainer,
I'm doing tests to use LVM snapshots to go back in case of apt dist-upgrade errors and I'm having a problem when a new kernel version is installed: I can not remove the snapshot because of a grub-mount. You can reproduce the problem as follows: root@sid:~# lvcreate -s -n snap -l 100%FREE /dev/sid-vg/root Logical volume "snap" created. root@sid:~# dpkg-reconfigure linux-image-5.3.0-2-amd64 /etc/kernel/postinst.d/initramfs-tools: update-initramfs: Generating /boot/initrd.img-5.3.0-2-amd64 /etc/kernel/postinst.d/zz-update-grub: Generating grub configuration file ...
