I should have mentioned having tried to make that work... but the simple answer
doesn't seem to.  The problem is I've had installonly_limit set to 5, to 0, to
10... and it always still fails (see this below).

I've tried the old plugin configuration as well.  Although I can change the
number of kernels it tries to get rid of... it still tries to remove my running
kernel!  I've manually set installonlypkgs=kernel, but without that (defaults)
it does the same thing.  I could not get it to install the kernel...

So taking a clue from your kmod comment I removed it, and now yum behaved
correctly, so the presence of the kmod-nvidia package is preventing the kernel
install from happening even though it was not going to remove the 1-42 kernel.

The installonlyn code may be parsing dependencies and failing the process even
though its not actually going to remove the kernel when the time comes.
Removing my video driver is also not good!

Could this be a package issue with the kmod-nvidia rpm or do you vote yum's
behavior?
