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.

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? – Codemonkey Dec 13 '18 at 13:23
  • In case your system is using grub2 issue this command: grub2-mkconfig -o /boot/grub2/grub.cfg – gillytech Apr 29 at 3:23
