If you mean Sebastian Ramacher's message https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=998169#39 saying "libodbc1 and odbcinst1debian2 could then be transitional packages with the compat symlinks that stay around at least for bookworm." I suppose that Sebastian did not know that the .so.2 sonames were already used for some time (I recall that the change in unixodbc was done in 2013). Was anything particular said on #debian-release? So I assume that only a transitional dummy package (without the symlinks) is needed. > I highly doubt that any package is linking via hard-coding to the > old soname version. Well, I think that the only potential issue is for old packages that were built before the soname change in 2013 and were removed from Debian at that time (thus are no longer rebuilt). But in practice, compat symlinks are not kept that long, are they? Note that given the fact that libodbc1 depends on libltdl7 (>= 2.4.6), which appeared in 2016, such packages from 2013 or earlier should already be broken. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
