# - the currently booted version
# - the kernel version we've been called for
# - the latest kernel version (as determined by debian version number)
# - the second-latest kernel version
#
# In the common case this results in two kernels saved (booted into the
# second-latest kernel, we install the latest kernel in an upgrade), but
# can save up to four. Kernel refers here to a distinct release, which can
# potentially be installed in multiple flavours counting as one kernel.
