i do tell apt specifically to not remove any kernel images
by using the option NeverAutoRemove in apt.conf
=========
APT
{
NeverAutoRemove { "linux-image.*"; }; // packages that should never
// considered for autoRemove
};
=========
usually after each kernel upgrade i'll remove the third oldest one
leaving me the most current one and the one that i used previously
if it seems to have been stable enough. i like doing some things
manually and this is one of them. the other one i prefer to do
myself is bring up the network connection. sometimes i don't need
it so prefer to leave the connection off...
also, just out of a good idea i usually keep a stable booting
partition. this saves me at times.
