Package: lintian
Version: 2.5.22.1
Severity: wishlist
Tags: patch
Dear lintian maintainers,
It would be nice if lintian could start bugging people about
"Pre-Depends: multiarch-support" in their debian/control file. At some
point multiarch-support should be removed from eglibc, but this cannot
be done as long as there still are dependencies on it. So we need to get
rid of these dependencies. Unfortunately we might still need them in
jessie, so just removing might be a bit too early. What would help
though is converting "Pre-Depends: multiarch-support" into "Pre-Depends:
${misc:Pre-Depends}" if the package in question uses dh_makeshlibs. Then
debhelper can be told to stop inserting that Pre-Dependency and all
affected packages will automatically drop it during their next build (or
binNMU). This way, removing multiarch-support becomes feasible for
jessie+1 and packages that use ${misc:Pre-Depends} keep being
backportable to wheezy and jessie.
Patch attached.
Helmut

+Info: The control file mentions multiarch-support in a Pre-Depends line.
+ Usually multiarch-support is inserted into Pre-Depends via ${misc:Pre-Depends}
+ by dh_makeshlibs. In order to be able to remove the multiarch-support package
+ from glibc without updating every package, Pre-Depends: ${misc:Pre-Depends}
+ should be used instead. Then multiarch-support can be removed by a change
+ in debhelper followed by a binNMU of all affected packages.
