From 7151da8b64dcc416986598e203c8b7c080789d7a Mon Sep 17 00:00:00 2001 From: Russ Allbery Date: Thu, 1 Jul 2010 12:15:46 -0700 Subject: [PATCH] Remove obsolete shlibs.local information Remove the instructions for how to create shlibs.local files and the encouragement to do so if one runs into errors with dpkg-shlibdeps, since the archive coverage for shlibs is now complete and writing a shlibs.local file is unlikely to be an appropriate solution to one's problem. --- policy.sgml | 83 +++++------------------------------------------------ 1 file changed, 7 insertions(+), 76 deletions(-) diff --git a/policy.sgml b/policy.sgml index 1e641e6..9a72be5 100644 --- a/policy.sgml +++ b/policy.sgml @@ -5470,8 +5470,13 @@ Replaces: mail-transport-agent

- As soon as the maintainer of bar1 provides a - correct shlibs file, you should remove this line - from your debian/shlibs.local file. (You should - probably also then have a versioned Build-Depends - on bar1 to help ensure that others do not have the - same problem building your package.) -
