Fedora 34, shadow-native/icedtea7-native, umask problems ?

[Jacob Kroon]

Hi,

I'm using Fedora 34 and OE-Core/Bitbake/layers from git master as of 
today, with reproducible builds. Sometimes when rebuilding my image I 
see sudden changes in file permissions (jumping back and forth) in the 
buildhistory output for two native recipes:

shadow-native: (OE-Core)
> -drwxr-xr-x -          -                  40 ./var/spool/mail
> +drwxrwxr-x -          -                  40 ./var/spool/mail

icedtea7-native: (meta-java)
> -drwxrwxr-x -          -                 120 ./usr/lib/jvm/icedtea7-native
> -drwxrwxr-x -          -                 800 ./usr/lib/jvm/icedtea7-native/bin
> --rwxrwxr-x -          -               15016 ./usr/lib/jvm/icedtea7-native/bin/apt
> --rwxrwxr-x -          -               15016 ./usr/lib/jvm/icedtea7-native/bin/extcheck
> --rwxrwxr-x -          -               15016 ./usr/lib/jvm/icedtea7-native/bin/idlj
...
> +drwxr-xr-x -          -                 120 ./usr/lib/jvm/icedtea7-native
> +drwxr-xr-x -          -                 800 ./usr/lib/jvm/icedtea7-native/bin
> +-rwxr-xr-x -          -               15016 ./usr/lib/jvm/icedtea7-native/bin/apt
> +-rwxr-xr-x -          -               15016 ./usr/lib/jvm/icedtea7-native/bin/extcheck
> +-rwxr-xr-x -          -               15016 ./usr/lib/jvm/icedtea7-native/bin/idlj
...

Before I start debugging them, does anyone have an obvious fix or hint 
for any of these ?

Regards,
Jacob
