If my new kernel blew up my system, I don't go scrounging around for boot disks, I pick the previous image on next boot.
Debian and Fedora's package managers both keep the last three kernels operating and in grub.
(This is a hassle for me since Fedora has had a long string of updates since 2.6.36 which was the last one that gave me working r/w HFS+ support, and i have to keep removing the second-to-last kernel manually with the package manager.)

- jerf 14y agoThat was an example. A bad one, I see. But it applies to any foundational library, not just the kernel. What's special-cased for the kernel in Debian et al is normal operating procedure for Nix.
