[Pkg-ace-devel] [devo-group] [PATCH] Request for review on a new library versioning scheme (versioned_so=2)

[Johnny Willemsen]

Hi Thomas,

The real disadvantage I see is that for debian package users things look
different out of the box than for any other user. This is also another
flag that has to be tested on various platforms, not doing that could
cause problems later on. What about changing the behavior of
versioned_so=1? With the symbolic link things don't change really for
users, only for packaging we have todo some updates.
