Comment 16 for bug 241368

The solution seems complicated, with all the prompts and so on. This *will* confuse users, and is something that can easily be hidden.

For casual users, the current kernel will be stable, and updates will only be for security.
We should keep the current and new kernels by default (so if the update does break anything, the user can recover).
Power users need to easily change this limit.
I suggest a simple script like the attached (but should get 'number to keep' from /etc/defaults/ etc). It can be easily triggered via a link in /etc/kernel/postinst.d/ - simply sucking up all the users disk space with limit (as at present) is not a solution, nor is expecting users to under stand what a kernel is or what is a 'good number' to keep around.
