Yes, linux-base should be installed on any system that needs an official
kernel package (i.e. it's not a container and doesn't use a custom
kernel) and then should never be removed.

I was working on the basis that a postrm script really must not fail as
this will leave the package in a weird state.  But then skipping those
hooks means that, for example, the initramfs image won't be deleted, and
GRUB won't remove the kernel's menu entry.  I don't know what's worse,
or how much it matters given the unlikeliness of removing linux-base.
