Description George R. Goffe 2016-08-23 20:57:23 UTC

Description of problem:

In updating this Fedora 23 system with kernel updates it appears that the kernel rpms are NOT removing the older kernel files.

Version-Release number of selected component (if applicable):
kernel-4.6.4-201.fc23.x86_64
kernel-4.6.5-200.fc23.x86_64
kernel-4.6.6-200.fc23.x86_64


How reproducible:
always

Steps to Reproduce:
1.upgrade with kernel rpm
2.
3.

Actual results:

The kernel config is updated but the older kernel files are not removoved:

entries in /boot/grub2/grub.cfg, /lib/modules and the support files in /boot are still in the system.

Expected results:

The older entries and files should be removed but perhaps this is something that the systems manager should be doing?

Comment 1 Justin M. Forbes 2016-08-23 21:44:22 UTC

Okay, I am a little bit confused about what you are doing here. How are you updating? dnf update, the graphical package manager, or raw rpm?  If it is dnf or the graphical manager, it should be leaving 3 kernels on the system, this is by design to protect you if you have an issue with the most recent kernel. This number can be changed by modifying 'installonly_limit=3' in '/etc/dnf/dnf.conf'.

Comment 2 George R. Goffe 2016-08-24 01:47:05 UTC

Justin,

Thank you for responding.

I'm using "dnf upgrade".

Here's my current lib/modules:

Somehow my dnf.conf has "5" for the limit and most of the files have 5 instances in them but /boot looks partially like this:

grub.cfg appears to be correct.


Your thoughts?

George...

Comment 3 Justin M. Forbes 2016-08-24 12:33:08 UTC

What version of systemd are you running? kernel-install was patched at one point to fix this.  This isn't something that the kernel package itself manages.

Comment 4 George R. Goffe 2016-08-24 14:50:15 UTC

Justin,

"my" systemd is at "systemd-222-14.fc23.x86_64"

George...

When this problem was resolved(?) was there anything suggested on just what to clean up? A cleanup script perhaps?

Comment 5 Justin M. Forbes 2016-08-24 15:39:27 UTC

Okay, this looks like a dup of 1321148 which has unfortunately still not been resolved.

Justin,

If you would like more info or if you need someone to test possible fixes, just let me know.

Thanks for your help,

George...
