Sorry, but I don't advise that. A few years back we had a few machines
running fedora, and at, was it 17? - they added preupgrade, they were
building and stuffing a *lot* of stuff in /boot, and were recommending at
least 500M. We just went to a 1G /boot by default.

500 MB should be fine for the /boot partition. I believe that is the
default with minimal installations on both CentOS 6 and 7.

I really wouldn't.  You can scrape by with that if you also make sure you
don't have dracut-config-rescue installed, but you can find yourself
struggling even with that, and so have to micromanage even further.  Upgrade a
kmod, watch /boot fill up, and find yourself in a bad place.

If you only had it set to 200M, I'd reinstall now.  If you had it set to 500M,
you'd cope.

Can I just change yum.conf with the setting installonly_limit=2 to
limit kernels installed too two?

Mine was about 500 MB and I removed some kernels because I got a warning 
the partition was getting full.


With only two kernels installed, 182 MB are used. I would suggest 1 GB 
and I believe that is what CentOS 7.3 will do by default.
