** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1780598/+attachment/5160957/+files/ProcEnviron.txt ** Attachment removed: "ProcCpuinfoMinimal.txt" https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1780598/+attachment/5160956/+files/ProcCpuinfoMinimal.txt ** Attachment removed: "Dependencies.txt" https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1780598/+attachment/5160955/+files/Dependencies.txt ** Description changed: In /etc/default/grub are two variables that enable customization of kernel options : GRUB_CMDLINE_LINUX_DEFAULT for non-recovery entries and GRUB_CMDLINE_LINUX for all entries (both recovery and non-recovery). It is not possible to specify kernel options to be used for recovery entries but not regular ones, which in my case is problematic as modesetting parameters are at a contradiction in those cases. I propose that the GRUB_CMDLINE_LINUX_RECOVERY would allow to do so. This requires exporting this variable in the grub-mkconfig script, so that it can be read by the 10_linux script. There, I propose to keep the usual behaviour when the variable has not been set, and to completely eschew it when the variable is set. I am reporting here as it appears that upstream grub 10_linux does not have a mechanism for recovery entries at all, so I think it is Ubuntu specific.
