The documentation for bionic mentions the new option, "debian-installer/add-kernel-opts": https://help.ubuntu.com/lts/installation-guide/amd64/apbs04.html
Note however that there is a mention of "if supported by the bootloader installer". Andrew: can you post full preseed file? There is also a mention of "options passed to the installer will be added automatically", so maybe you can try passing kernel options through the installer kernel options? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/581796 Title: grub-installer ignores grub2/linux_cmdline_default in preseed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/581796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
