Do I need to clean up the boot menu?

[Danielx64]

Now i'm running a basic linux server that is used to develop and test applications written in PHP. It doesn't have much: Maria DB, litespeed standard and a bunch of different PHP versions. Now I been running yum update every now and then and when restarting the box I can see that there an extra item added to the boot menu. Can someone please tell me why that would happen and do I need all those extra versions/option?

 

Thank-you

looks like these entries are for older kernels. if you don't need them anymore, uninstall them and do a grub-update and they will be gone.

Ok after a look look on how to remove the old kernels I managed to get about 400M of space back. For anyone else who wanting to remove the old kernels I used:

yum install yum-utils
package-cleanup --oldkernels --count=1
