Yes, the default behaviour is to leave 2 or at most 3 versions of kernel 
*if* you always install the latest kernel (automatically) via the 
meta-package linux-image-generic. You can see what versions will be kept 
(by apt-get autoremove) by looking at 
/etc/apt/apt.conf.d/01autoremove-kernels. This file is auto-generated 
when a kernel package is installed by the post-install script 
/etc/kernel/postinst.d/apt-auto-removal which comes with apt. Reading it 
helps the understanding. :-)

If you install *manually* a particular version of the kernel, `apt-get 
autoremove` will not touch it.

Regards,
ST
