Description of problem: The instructions[1] of how to append parameters to Grub's grub.config file is obsolete on recent releases of Fedora. The file /boot/grub/grub.conf doesn't exist anymore. The way to do it now is (tested on Fedora 20): 1 - Edit /etc/default/grub 2 - Append information at the line GRUBCMDLINELINUX=" ... console=tty0 console=ttyS0,115200 ... ") 3 - Regenerate the /boot/grub2/grub.cfg file with the command "grub2-mkconfig -o /boot/grub2/grub.cfg" Link: [1] http://docs.fedoraproject.org/en-US/Fedora/18/html/Virtualization_Administration_Guide/sect-Virtualization-Troubleshooting_-Troubleshooting_with_serial_consoles.html Additional info: The documentation is refered to version 18 where it should work, but as we don't have a documentation in a most atual release of Fedora for that subject, you can write a note for the users of most recent releases of Fedora that came with Grub2, where the procedure is according with that listed above.
Yes, the file /boot/grub/grub.conf is gone and we need to indicate that for non uefi boards, it is /boot/grub2/grub.cfg While fixing up grub for some troubleshooting, perhaps the submenu option can be implemented, taking the linux releases following the first to the recovery / rescue version Current Linux submenu 'Additional Fedora entries' { Previous Linux Previous Linux Recovery Linux } # end submenu I should not have to do this manually, though the change is trivial.
Hello Is this any help: http://docs.fedoraproject.org/en-US/Fedora/21/html/System_Administrators_Guide/ch-Working_with_the_GRUB_2_Boot_Loader.html
Hi Steven, In response to your question, it is not. Please look at the following example There are several menuentry items. I want to be able to automatically isolate the first "menuentry without modification but to encapsulate the remaining menu entries ending with the rescue entry. Encapsulate with a submenu, as grub2 does it for other os's later on in the list. Example menuentry for current Fedora kernel submenu 'encapsulate the following' { menuentry prevous Fedora kernel menuentry previous to previous Fedora kernel menuentry Rescue entry } #end submenu entry With two lines of text, I clean up a lot of useless screen clutter. The submenu entries are available by clicking on the displayed submenu title. Why do I want to do that? I multiboot, Fedora (up to 3 different versions), Centos, Windows, a total of up to 5 distributions. Grub2 does create a submenu for all the Guest OS's but not the current version. Why not for the first current version? It may have to be a include a new menu entry somewhere after 30 and before 40. 00_header 10_linux 20_linux_xen 20_ppc_terminfo 30_os-prober 35 " New facility to signal that a submenu entry is desired". 40_custom 41_custom I hope this clarifies comment 1.
5 disks, each with a full grub2.cfg My menu is almost 25 lines deep. I manually isolate the current kernel and rework the grub.cfg as I described above Result main Fedora xx #1 Submenu "Advanced Features" Guest Fedora xx #2 Submenu "Advanced Features" Guest Fedora xx #3 Submenu "Advanced Features" Guest Fedora xx #4 Submenu "Advanced Features" Guest Fedora xx #5 Submenu "Advanced Features" Otherwise main Fedora xx #1 previous kernel #1 previous kernel #2 previous kernel #3 rescue kernel #4 Guest Fedora xx #2 Submenu "Advanced Features" Guest Fedora xx #3 Submenu "Advanced Features" Guest Fedora xx #4 Submenu "Advanced Features" Guest Fedora xx #5 Submenu "Advanced Features"
I'm closing this bug as part of a Bugzilla cleanup effort. The most likely reason is that the bug has been opened either against a component we no longer publish, or against Release Notes for an EOL release.
