> Some of the issues related to TarMK revision gc should be back ported to the branches. This issue is for keeping track of which issues and which svn revisions we consider for back porting. The task consists of the following steps:
> # Identify issue to back port
> # Merge the respective commits into a private forks of the 1.0 and 1.2 branches
> # Run tests on builds from the private forks
> # On success merge the private forks to the 1.0 and 1.2 branches and update the fix versions of the respective issues. This probably requires manually updating the svn merge info with the respective svn revisions. 
> [~dhasler]: FYI
> [~alex.parvulescu], [~frm]: please refrain from merging potential conflicting changes into the branches in the meanwhile.
