Since when does yum remove old kernels automatically? Seems a bit dangerous to me. What if there's a problem and one needs a fallback?

Dan.

See  /etc/yum/pluginconf.d/installonlyn.conf.

One old one is always left (tokeep=2).

But because only kernel RPMs are managed, yum updates to the kerenl won't work if you use external modules like nvidia or ntfs. Yum will try to remove the old kernel and dependencies of the unremoved modules will force it to abort. Keeping the proliferation of kernels under control isn't a bad idea, but it still needs some work.
