We've some Ubuntu 16.04 servers.
unattended-upgrades are automatically enabled since 16.04 and the boot partition is on a separate partition.
Due to the automatic security updates the boot partition is running out of space with new kernels.
We can't just reboot the systems so the machine is still using the penultimate kernel.
Which kernels should I remove? All but the currrent, the oldest and the newest?
Do you guys have some recommendations?
I have also noticed that the newest kernel has the status "Half Configured". This kernel would probably not work so should I remove this one and use the an older kernel.
