Revision 24684, 8.5 KB checked in by broder, 14 years ago (diff)
debathenify-openafs uses bashisms, so fix the shebang. This change has been in use in production use since Debian finally switched to using dash for /bin/sh a few months ago

54# Get all of the packages named linux-image-*.  This list includes
55# three types of packages:
56#  - Actual kernel images (e.g. linux-image-2.6.24-19-generic)
57#  - Metapackages (e.g. linux-image-generic) which are used to keep
58#    kernel images up to date
59#  - Meta-metapackages which depend on other metapackages; these
60#    exist for transitional reasons or to provide more generic names
61#    (e.g. linux-image-amd64 depends on linux-image-2.6-amd64 in
62#    lenny)
63#
64# We can distinguish actual kernel images from metapackages by looking
65# at the source package; actual images will have the source "linux"
66# (Ubuntu) or "linux-2.6" (Debian) while both kinds of metapackages
67# will have the source "linux-meta" (Ubuntu) or "linux-latest-2.6"
68# (Debian).
