I was probably exaggerating slightly; I did not do the calculations.
However, each kernel-source package represents 25M of binary and 30M of
source packages, which is a significant amount of space both in the main
archive and on the CD set, not to mention the benefits in simplicity and

Another thing that concerns me is the upgrade process.  The practice of
overwriting the running kernel and modules results in a risky, interactive
installation process, and makes it impossible to back out to the old kernel
unless the user takes appropriate measures.

I noticed that the current 2.4.20 kernel-image packages in unstable have
taken a different approach.  When the i386 kernel was updated to include the
ptrace fix, it was built as a separate binary package, 2.4.20-1-<subarch>
rather than 2.4.20-<subarch>.  This allowed both kernels to be installed
simultaneously, and the upgrade easily reverted.  Users who had installed
the kernel-image-2.4-686 metapackage were still automatically upgraded.
