65# three types of packages:
66#  - Actual kernel images (e.g. linux-image-2.6.24-19-generic)
67#  - Metapackages (e.g. linux-image-generic) which are used to keep
68#    kernel images up to date
69#  - Meta-metapackages which depend on other metapackages; these
70#    exist for transitional reasons or to provide more generic names
71#    (e.g. linux-image-amd64 depends on linux-image-2.6-amd64 in
72#    lenny)

74# We can distinguish actual kernel images from metapackages by looking
75# at the source package; actual images will have the source "linux"
76# (Ubuntu) or "linux-2.6" (Debian) while both kinds of metapackages
77# will have the source "linux-meta" (Ubuntu) or "linux-latest-2.6"
78# (Debian).
