[yocto] Unclear sstate-cache dir permissions

[Marco]

Hello,
I am trying to share a sstate-cache between two (or more) users in a
shared directory.
Although I set the directory owner, group and permissions I face to a
weird condition that I don't understand.
Particularly why some directories don't have the group write
permisisons that drive me to a buld failure for mambers of the group.

I wonder if I am doing something wrong or I have an unexpected issue.


koan at kmobile:sstate-cache$ ll
totale 1028
drwxrwxr-x   2 koan devgroup 4096 set 14 15:32 00
drwxrwxr-x   2 koan devgroup 4096 set 14 14:37 01
...
drwxr-xr-x   2 koan devgroup 4096 set 14 15:31 1d
drwxrwxr-x   2 koan devgroup 4096 set 14 15:31 1e
...
drwxr-xr-x   2 koan devgroup 4096 set 14 15:32 27
drwxrwxr-x   2 koan devgroup 4096 set 14 15:32 28
...
etc...


Any help would be greatly appreciated.

Thank you
