This may block Alpha if it affects things at install time, I'll try and test that when we have a viable install image. dracut-026-72.git20130320 The problem is still present in F20. Do you need any additional information? Yes, because I don't think it is. I've done many, many F20 installs, including one just this morning, and not seen this. I don't recall problem being in F19, started happening after upgrading to F20 with fedup.
This is what was generated after installing a new kernel (I purposely installed rawhide-nodebug kernel just to show grub config). Contents of /boot/efi/EFI/fedora/grub.cfg:

This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. this got fixed, IIRC. |
The new /etc/kernel/postinst.d/51-dracut-rescue-postinst.sh creates kernels with this kind of filename: vmlinuz-2000656e56500583cc9b884bb121a7b9-rescue initramfs-2000656e56500583cc9b884bb121a7b9-rescue.img To grub, these names order higher than typical Fedora kernel names: vmlinuz-3.9.0-0.rc3.git0.5.fc20.x86_64 initramfs-3.9.0-0.rc3.git0.5.fc20.x86_64.img So when I run grub2-mkconfig , I get something like the grub config snippet that comes after this description: note that the 'Fedora' entry is for the rescue kernel, as is the first entry on the 'Advanced options for Fedora' sub-menu. Obviously, we don't want the rescue kernel to be the default when someone runs grub2-mkconfig for any reason (or when the installer does it, if the rescue kernel is present at that point). It should be the last entry in 'Advanced options', ideally. pjones writes: <pjones> we're not changing the ordering function; dracut should be doing something smarter about what it creates. So you get to rename the rescue images such that they will order dependably *after* the real kernels. ### BEGIN /etc/grub.d/10_linux ### menuentry 'Fedora' --class fedora --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-a749ca4b-0cea-4db0-883d-5c036d89e5c5' { savedefault load_video insmod gzio insmod part_msdos insmod ext2 set root='hd0,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 --hint='hd0,msdos1' a96e9316-f248-44e4-9197-2d686791a8bb else search --no-floppy --fs-uuid --set=root a96e9316-f248-44e4-9197-2d686791a8bb fi echo 'Loading Linux 2000656e56500583cc9b884bb121a7b9-rescue ...' linux /vmlinuz-2000656e56500583cc9b884bb121a7b9-rescue root=/dev/mapper/vg_adam-lv_root ro quiet rhgb fbcon=rotate:3 slub_debug=- echo 'Loading initial ramdisk ...' initrd /initramfs-2000656e56500583cc9b884bb121a7b9-rescue.img } submenu 'Advanced options for Fedora' $menuentry_id_option 'gnulinux-advanced-a749ca4b-0cea-4db0-883d-5c036d89e5c5' { menuentry 'Fedora, with Linux 2000656e56500583cc9b884bb121a7b9-rescue' --class fedora --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-2000656e56500583cc9b884bb121a7b9-rescue-advanced-a749ca4b-0cea-4db0-883d-5c036d89e5c5' { savedefault load_video insmod gzio insmod part_msdos insmod ext2 set root='hd0,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 --hint='hd0,msdos1' a96e9316-f248-44e4-9197-2d686791a8bb else search --no-floppy --fs-uuid --set=root a96e9316-f248-44e4-9197-2d686791a8bb fi echo 'Loading Linux 2000656e56500583cc9b884bb121a7b9-rescue ...' linux /vmlinuz-2000656e56500583cc9b884bb121a7b9-rescue root=/dev/mapper/vg_adam-lv_root ro quiet rhgb fbcon=rotate:3 slub_debug=- echo 'Loading initial ramdisk ...' initrd /initramfs-2000656e56500583cc9b884bb121a7b9-rescue.img } menuentry 'Fedora, with Linux 3.9.0-0.rc2.git0.4.fc20.x86_64' --class fedora --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-3.9.0-0.rc2.git0.4.fc20.x86_64-advanced-a749ca4b-0cea-4db0-883d-5c036d89e5c5' { savedefault load_video set gfxpayload=keep insmod gzio insmod part_msdos insmod ext2 set root='hd0,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 --hint='hd0,msdos1' a96e9316-f248-44e4-9197-2d686791a8bb else search --no-floppy --fs-uuid --set=root a96e9316-f248-44e4-9197-2d686791a8bb fi echo 'Loading Linux 3.9.0-0.rc2.git0.4.fc20.x86_64 ...' linux /vmlinuz-3.9.0-0.rc2.git0.4.fc20.x86_64 root=/dev/mapper/vg_adam-lv_root ro quiet rhgb fbcon=rotate:3 slub_debug=- echo 'Loading initial ramdisk ...' initrd /initramfs-3.9.0-0.rc2.git0.4.fc20.x86_64.img } menuentry 'Fedora, with Linux 3.9.0-0.rc1.git2.1.1.fc19.x86_64' --class fedora --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-3.9.0-0.rc1.git2.1.1.fc19.x86_64-advanced-a749ca4b-0cea-4db0-883d-5c036d89e5c5' { savedefault load_video set gfxpayload=keep insmod gzio insmod part_msdos insmod ext2 set root='hd0,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 --hint='hd0,msdos1' a96e9316-f248-44e4-9197-2d686791a8bb else search --no-floppy --fs-uuid --set=root a96e9316-f248-44e4-9197-2d686791a8bb fi echo 'Loading Linux 3.9.0-0.rc1.git2.1.1.fc19.x86_64 ...' linux /vmlinuz-3.9.0-0.rc1.git2.1.1.fc19.x86_64 root=/dev/mapper/vg_adam-lv_root ro quiet rhgb fbcon=rotate:3 slub_debug=- echo 'Loading initial ramdisk ...' initrd /initramfs-3.9.0-0.rc1.git2.1.1.fc19.x86_64.img } }
