script copies certain kernel versions and the initrd images to `EFI/proxmox/`

The following kernel versions are configured by default:
* the currently running kernel
* the version being newly installed on package updates
-* the two latest kernels
-* the latest version of each kernel series (e.g. 4.15, 5.0).

+* any manually selected kernels (see below)
The ESPs are not kept mounted during regular operation, in contrast to `grub`,
which keeps an ESP mounted on `/boot/efi`. This helps to prevent filesystem
