Note there's a double space after the '^ii' which isn't shown unless you click the command to cut & paste. Good command!

Nifty, but two problems (i'm using ubuntu 10.10): [1] It removes kernels newer than the one running (which are present if you upgrade and don't reboot immediately) and [2] It removes meta-packages '/linux-(headers|image)-generic/' which causes a chain of unintended consequences (e.g., 'linux-generic' has unmet dependencies) and prevents auto-upgrading to future kernels.

i am using Ubuntu 11.4 and it tries to remove the actual kernel i am running right now!!! DANGEROUS!!!!! use #uname -a before, to see the actual kernel

Indeed, this is a bad implementation of a good idea.
