Hi,
since Scale 5.1.3, there's also a new parameter for filesets to control the
behaviour of umask & ACLs:
man mmchfileset|mmcrfileset
--allow-permission-inherit PermissionInheritMode
inheritAclOnly
Specifies that permissions of a newly created object will be inherited only
from its parent's NFSv4 ACL.
inheritAclAndAddMode
Specifies that permissions of a newly created object will be inherited from
its parent's NFSv4 ACL and the special entries OWNER, GROUP, and EVERYONE will
use the provided mode and the umask from the open() or creat() call to set the
new mode permissions.
With the default inheritAclOnly, umask is ignored and only the inherited ACLs
will be applied to newly created files.
With inheritAclAndAddMode the umask is used in addition to inherited ACLs for
new files.
Regards,
Stefan
