FYI, this is expected. The locales have numerous copies of the same files for the same locales. So to save space there is a step that runs and identifies the duplicates and hard links them. (This helps a lot for the sstate-cache for instance). It likely wouldn't be difficult to determine the link count 'issue' and simply link to a different file for subsequent links... but I'm no longer sure where the linking occurs that does all of this. --Mark > > I’ll report back if the rest of the build completes. > > > > Bryan > > > > > -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
