Bug description:
SRU Justification
Impact: Our kernel packaging currently has support for backporting
kernels to older releases. This includes appending ~BACKPORT_SUFFIX to
the version string for the backport kernel, where BACKPORT_SUFFIX is
defined in update.conf. We need to start doing similar forward ported
kernels, but BACKPORT_SUFFIX should be appended using a + rather than
a ~. Our kernel packaging cannot easily determine whether a + or a ~
is appropriate.
Fix: Move the leading character into BACKPORT_SUFFIX, and do not
insert any leading characters from the kernel packaging scripts. Since
the script which generates update.conf has access to information from
kernel-series, it can more easily determine whether + or ~ is the
appropriate leader.
Test Case: Run through the normal steps for updating a backport
kernel. The version string generated should have ~SERIES for a
backport to an older series, and +SERIES for a backport to a newer
series.
Regression Potential: Backport kernels could end up with an incorrect
version strings. Since all kernel uploads undergo review, any such
errors should be caught before uploading.
