This script figures out and munges +# version strings. The goal is: +# +# * Set the package name to dpdk-modules-$(KVERS) where $(KVERS) is the +# major kernel revision plus the debian subrevision and whatever +# architecture string is appropriate if building against the stock Debian +# kernels. $(KVERS) should be identical to the version component contained +# in the Debian kernel package names (in other words, the ABI version, not +# the package version). +# +# * Make the package depend on linux-image-$(KVERS) (= version) as appropriate +# for the kernel version that we're building against. Use depend as the +# kernel ABI is not stable and it's not guaranteed that a module built +# against a version of the headers will work under a different kernel. +# +# * Save the version number of the binary package in debian/VERSION for later +# use by dh_gencontrol. This will be the version number of the source +# package followed by a + and the version number of the kernel package that +# we're building against. If the kernel package version contains an epoch, +# try to hack our way into doing the right thing by using that epoch number +# as our own. This isn't quite the right thing, but seems reasonably good. +# +# This script generates debian/control from debian/control.template using sed. +# Unfortunately, substvars cannot be used since the name of the package is +# modified and substvars happens too late.
