Offer purging of old kernels

[Pander]

Please consider an option to purge old kernels. This feature should take into account only kernels except the latest and one but latest. Also a check could be made that successful boots have been made with the latest and one but latest kernel since booting from these old kernels.

Especially on systems with limited space and inexperienced users this will prevent cumulation of installed kernels that never get purged from the system and waisting resources in terms of disk space.

Optionally this feature could also be made available in software-center and computer-janitor.

Status changed to 'Confirmed' because the bug affects multiple users.

Few months ago I installed Ubuntu 13.10 and selected "automatic" partition of hard drive. To my delight Ubuntu installer choosed *only 256 MB* for /boot partition.

Today during regular update /boot run out of space and update failed, and this is only few months of working with Ubuntu with "default" installation!

IMO this is serious defect.

In bug #699806 /boot running out of space leads to unbootable system.

This would be particularly useful when Ubuntu was installed with full disk encryption, which leads to a very small /boot partition by default.
