boot directory 85% - What to delete?

[wrender]

After installation of CloudLinux, my /boot directory is at 85%. What can be removed to give some more room.
Removing the first file at 41MB would solve the issue, is this file necessary? Can I just rm it?

[info]

Its not recommended to delete files in /boot manually. What i would do is detect what is the current kernel with:

 rpm -q kernel

After that, delete older kernels. In your list it could be something like:

rpm -e -3.10.0-229.20.1.el7.x86_64

Thanks for the suggestion. Ill try that. It seems that I would get a great deal more space by
removing initramfs-0-rescue-230913a5ff624ce7b6d4e4292f96171a.img which is 40MB.
Is this a bad idea?
