But this does not work satisfactory all the times. Given you have a directory 
on one system that everybody within a certain groups should be able to access 
completely. Then you scp a file that is not group writable (e.g. from a cd) 
to it. Which default ACL for a group will makes the file writeable or 
chmodable for everyone from this group? Afaik there is no such ACL. The best 
approaches except giving everybody chmod/chown acces via sudo would be to 
mount vfat filesystem into the directory, because it accepts a gid/uid mount 
option to enforce a certain gid for all contents, or to use a fuse wrapper 
filesystem that manages the permissions, but I am not sure, whether this is 
possible or does already exist.
