I have one kernel installed currently, 3.10.0-327.28.3.

In my /boot directly, I have what looks like a lot of stuff that package-cleanup perhaps missed:

 -rw-r--r-- 1 root root 17M Aug 28 18:00 initramfs-3.10.0-327.10.1.el7.x86_64.img -rw-r--r-- 1 root root 17M Aug 28 18:00 initramfs-3.10.0-327.28.2.el7.x86_64.img -rw-r--r-- 1 root root 20M Aug 29 00:46 initramfs-3.10.0-327.28.3.el7.x86_64.img -rw-r--r-- 1 root root 17M Aug 28 17:00 initramfs-3.10.0-327.28.3.el7.x86_64kdump.img -rw-r--r-- 1 root root 17M Aug 28 18:01 initramfs-3.10.0-327.4.5.el7.x86_64.img

Can I remove those 3 files safely? They look like they belong to older kernels.

    @user4556274 package-cleanup is ignoring these files for some reason. Commented Aug 29, 2016 at 8:32

Yes. Those files are from previous kernel installation. You may had upgraded kernel hence old kernel files along with their initramfs files are residing on /boot partition.

If you want to clean up them then you can remove by using distribution-specific utility like apt-get.

Once you remove, then execute the following command to remove those kernel's entry from grub.cfg file

grub-mkconfig -o /boot/grub/grub.cfg

if you have legacy grub installed then modify the /boot/grub/grub.conf file manually.

    Is it harmful just to delete the files and not change the grub config file? Commented Dec 13, 2018 at 13:23

    In case your system is using grub2 issue this command: grub2-mkconfig -o /boot/grub2/grub.cfg Commented Apr 29, 2020 at 3:23
