Description of problem:

installing (and reinstallng)kernel-core-4.1.10-200.fc22.x86_64.rpm doesn't and the new entry to grub.cfg 

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:

Actual results:
No entry for new kernel

Expected results:

Additional info:

I ran the kernel-install script by itself:
# /bin/kernel-install add 4.1.10-200.fc22.x86_64 /boot/vmlinuz-4.1.10-200.fc22.x86_64

no error, but no entry in grub.cfg.

The kernel files are in /boot:

ls /boot/*200*

On today's upgrade to kernel-4.2.3-200 , same problem.

grep  -B 1 -A 5 kernel.x86_64\ 4.2.3-200.fc22  /var/log/dnf.log | grep -v DEBUG
  kernel.x86_64 4.2.3-200.fc22

Comment 2 Jóhann B. Guðmundsson 2015-10-21 15:11:02 EDT
kernel-install does not support create/generating grub configuration files. 

It only supports creating a boot loader entry's in accordance with the boot loader specification which in turn should be usable by bootloaders that confirm with that specification.

Fedora carry's downstream hack [1] that just calls /sbin/new-kernel-pkg which in turn generates those grub entries so a) you dont have grubby package installed or b) grubby/new-kernel-pkg is not generating those boot entries

Re-assigning to correct component.

Comment 3 reescf 2016-01-11 14:18:57 EST
This didn't work in Fedora 21 and doesn't work in Fedora 23 either. It *does* work on a system I configured to use EFI booting, but it does not work on a system using BIOS booting. 

grubby seems to update a config file in /etc, but does not touch the config file in /boot/grub2, and does not seem to use information from /etc/default/grub or /etc/grub.d effectively. (So the config file it creates in /etc wouldn't boot the system even if it were accessible on first booting, which it isn't.)
Comment 4 reescf 2016-01-12 11:33:36 EST
As far as I can tell, on my system the problem is that

readlink -f /etc/grub2.cfg

returns /etc/grub2.cfg. It does not return /boot/grub2/grub.cfg. Hence, grubby is only ever going to update the former, which is useless. It never touches the latter.
Comment 5 Fedora End Of Life 2016-07-19 14:12:48 EDT
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
