I guess that whilst the default task umask is 022, some chmod operations may be run to change permissions that don't match the umask. These are correctly captured by the sstate archive but not preserved by tar at extraction. I wonder if the correct fix is to all -p to the tar unpack command in sstate.bbclass? In many cases it would execute under pseudo so there wouldn't be this issue but a native populate_sysroot wouldn't be under pseudo do we'd only see that here... Cheers, Richard
