# Mark as not-for-autoremoval those kernel packages that are:
# - the currently booted version
# - the kernel version we've been called for
-# - the latest kernel version (determined using rules copied from the grub
-# package for deciding which kernel to boot)
-# - the second-latest kernel version, if the booted kernel version is
-# already the latest and this script is called for that same version,
-# to ensure a fallback remains available in the event the newly-installed
-# kernel at this ABI fails to boot
-# In the common case, this results in exactly two kernels saved, but it can
-# result in three kernels being saved. It's better to err on the side of
-# saving too many kernels than saving too few.
+# - the latest kernel version (as determined by debian version number)
+# - the second-latest kernel version
#
-# We generate this list and save it to /etc/apt/apt.conf.d instead of marking
-# packages in the database because this runs from a postinst script, and apt
-# will overwrite the db when it exits.
-
+# 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.
