[opensuse] grub2 does not reflect installation of new kernel - how to add entry?
All, As part of troublshooting the acpi backlight bug in 13.1, https://bugzilla.novell.com/show_bug.cgi?id=887629 there was a request I install and test the 3.15 kernel from kernel:/stable/standard. The install went fine after adding the repository and was done via 'zypper up -t package'. The zypp.conf multiverison preserved the 3.11 kernel: kernel-default-devel-3.11.10-17.2.x86_64 kernel-default-devel-3.15.6-2.1.gedc5ddf.x86_64 kernel-desktop-3.11.10-17.2.x86_64 kernel-desktop-3.15.6-2.1.gedc5ddf.x86_64 kernel-desktop-devel-3.11.10-17.2.x86_64 kernel-desktop-devel-3.15.6-2.1.gedc5ddf.x86_64 kernel-devel-3.11.10-17.2.noarch kernel-devel-3.15.6-2.1.gedc5ddf.noarch kernel-firmware-20140624git-35.1.noarch kernel-source-3.11.10-17.2.noarch kernel-source-3.15.6-2.1.gedc5ddf.noarch kernel-syms-3.11.10-17.1.x86_64 kernel-syms-3.15.6-2.1.gedc5ddf.x86_64 kernel-xen-devel-3.11.10-17.2.x86_64 kernel-xen-devel-3.15.6-2.1.gedc5ddf.x86_64 The problem is that grub2 only reflects a single menu entry for 'openSuSE 13.1' and no second entry to boot the 3.11 kernel. Now with good-old grub, I'd simply edit /boot/grub/menu.lst and add a new menu entry for 3.11. But what do you do for grub2? Also, why doesn't the kernel install create menu entries like it did in 11.4? From 11.4 updates, I had a page full of kernels to choose from. Now, just 1? What says the brain-trust? -- David C.

Unless the appropriate 'mkinitrd' and 'grub2-install' (with suitable parameters) were run, then you have what I'd expect. Grub2 is NOT dynamic. It doesn't scan at at run time in the way that its predecessors did. That why you need grub2-install. The 'zypper' _should_ have caused those two to be triggered. You should check that time/date on your kernels in /boot (and that the maps etc are all there for .15) and the time/date on the grub2/grub.cfg. Oh, and your log :-) Of course you could also re-run mkinitrd and grub2-install manually :-) I'd probably have more detailed questions about your /etc/config/* but its been a long day and I'm tired. -- "Education must precede motivation."

All,
As part of troublshooting the acpi backlight bug in 13.1, https://bugzilla.novell.com/show_bug.cgi?id=887629 there was a request I install and test the 3.15 kernel from kernel:/stable/standard.

kernel-default-devel-3.11.10-17.2.x86_64 kernel-default-devel-3.15.6-2.1.gedc5ddf.x86_64 kernel-desktop-3.11.10-17.2.x86_64 kernel-desktop-3.15.6-2.1.gedc5ddf.x86_64 kernel-desktop-devel-3.11.10-17.2.x86_64 kernel-desktop-devel-3.15.6-2.1.gedc5ddf.x86_64 kernel-devel-3.11.10-17.2.noarch kernel-devel-3.15.6-2.1.gedc5ddf.noarch kernel-firmware-20140624git-35.1.noarch kernel-source-3.11.10-17.2.noarch kernel-source-3.15.6-2.1.gedc5ddf.noarch kernel-syms-3.11.10-17.1.x86_64 kernel-syms-3.15.6-2.1.gedc5ddf.x86_64 kernel-xen-devel-3.11.10-17.2.x86_64 kernel-xen-devel-3.15.6-2.1.gedc5ddf.x86_64
The problem is that grub2 only reflects a single menu entry for 'openSuSE 13.1' and no second entry to boot the 3.11 kernel.

I'm not sure what the algorithm by which grub-install determines which kernel is the one at the first selection and not in the 'Advanced options'. I could probably drill down into the code but not right now. David, why you don't you read /boot/grub2.grub.cfg Scroll down to the "Advanced options" and read on from there to see if there is a ".15". Or use vi and search. Or grep.

Anton, Thanks, that's what I did. I guess the issue I'm trying to get at is "I want to see the kernels as menu entries instead of 'submenus'". That was what was confusing as heck to begin with. Being used to grub and being used to grub2 on Archlinux, the kernels are always presented at menu entries themselves instead of submenus of 'Advanced Options'. I have no complaint about the workings of grub2, boots fine, but I am not nearly as familiar with the menu setup as I was with grub. At first blush, the grub.cfg file is quite a bit more involved that grub itself. It's easy to see how it sources /etc/grub.d/##_entries, but it is not at all apparent what the requirements are for all the "module soup" entries. E.g.: function load_video { blah... } if loadfont $font ; then set gfxmode=auto load_video insmod gfxterm set locale_dir=$prefix/locale set lang=en_US insmod gettext fi terminal_output gfxterm insmod part_msdos insmod ext2 blah... insmod gfxmenu loadfont ($root)/boot/grub2/themes/openSUSE/DejaVuSans-Bold14.pf2 loadfont ($root)/boot/grub2/themes/openSUSE/DejaVuSans10.pf2 loadfont ($root)/boot/grub2/themes/openSUSE/DejaVuSans12.pf2 loadfont ($root)/boot/grub2/themes/openSUSE/ascii.pf2 insmod png blah... The menu entries: menuentry 'openSUSE 13.1' --class 'opensuse-13-1' blah... then submenu 'Advanced options for openSUSE 13.1' $menuentry_id_option blah... menuentry 'openSUSE 13.1, with Linux 3.15.6-2.gedc5ddf-desktop' ... menuentry 'openSUSE 13.1, with " (recovery mode)' ... menuentry 'openSUSE 13.1, with Linux 3.11.10-17-desktop' Where in the config can I tell it to pull the menu entries out of the "submenu 'Advanced options...'" and make them top-level menu entries itself? -- David C.

The man pages eventually lead to the fact that the generation of the grub2 config file is entirely programmatic and the code is in /etc/grub.d There is also a graphical tool for customising. grub-customizer (1) - a graphical grub2/burg editor With that, you can 'edit' the entries out of the sub menu to the top level, as well as alter colour, theme, screen size and more. -- Objects in calendar are closer than they appear. -- Jim Duncan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Just used that to make the grub2 menu appear as * all desktop entries are at top level * all 'recovery' entries are in the second level menu under 'Advanced settings".

I don't know about the algorithm either, but I have to think the root cause of any menu.cfg that doesn't show the latest installed kernel as the default kernel is the same as with Grub Legacy. Unless I miss my guess, it's perl-Bootloader that makes the determination, one in which I think a kernel installed from an optional repo for a release version of openSUSE might never be considered top priority/first choice. The other possibility is it's not about the repo version, but about the new kernel being a different flavor than that originally (or possibly last) installed (e.g. kernel-desktop originally, kernel-default most recent). If so, or if I'm close to right that either is the way it is, it's IMO a good reason for not having Grub2's initial screen offer only a choice between the default kernel and opening a submenu. I very much prefer a boot menu that may offer a need to scroll over one containing any submenu. If Grub2 offers a configuration option to not have any submenu, and if I was actually using Grub2, I'd be using that option. ;-) -- "The wise are known for their understanding, and pleasant words are persuasive."

grub-install does not create grub.cfg, it is done by grub-mkconfig. It sorts all found kernel names in descendant order and takes the first. All others are put in Advanced menu. Now algorithm used to sort may not be optimal, 13.2 has patch that changes sort to be more in line with RPM version sort. grub in 13.2 also supports disabling submenus so all entries a put in flat list. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
