+# 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)
+# 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.
+#
+# 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.
