I remember from my Debian days that there were two kernels installed. That way, the modules from the old kernel version would still be around as it was the other kernel that got overwritten after kernel upgrades. This was really convenient.
Debian may not be a rolling release but security updates are very frequent, or else I may have missed your point.
