CentOS - Oct 2017 - /boot partition too small

Do i need to do something special or is it as easy as:
- save the contents of the current /boot?- umount /boot and change the
/etc/fstab so it doesn't mount again-??create a boot directory that is in
the?root ?filesystem- copy the contents back
I realize the physical/current /boot will be a waste of space but it's not
that big so?it's fine.???
I thought i probably have to make configuration changes of some sort.
Again I apologize in advance since I am not really good at this (partition/file
system).? I have tried searching but am never sure exactly what I should try.??
I need to find the "for dummies" version(s) of this. Thanks again.
KM

Indeed, /boot does not need to be a separate partition. I have /boot 
within the root filesystem on my test boxes where I know I will need to 
install many / all kernels for testing / development purposes for the 
specific reason that I do not need to set a size for /boot and it can 
just consume whatever it needs from the rest of the filesystem.

You'll also have to reinstall Grub. The wiki has information on this.

Thanks again.

Assuming you have backups, if something should go south, you might want to try 
out the Gparted boot-iso.

Using Gparted you should be able to shrink some of the other partitions, and 
then grow the boot partition.

More info on:
https://gparted.org/index.php

If you have another non-critical computer to test using Gparted on, do that 
first before doing it "for real".

Hope this helps.

Wait a sec, this was LVM right?
Not sure if Gparted supports that yet.
