**Andreas Wiese** say that if you have common group id across all hosts you may solve your issue with `setgid` bit and ACL

I ask question http://unix.stackexchange.com/questions/273144/predefined-group-ids-across-linux-distros/ 

After own research found that such group exist across all touched distros: `sys` group share id `3` on Debian, Ubuntu, RedHat, Fedora, CentOS, Suse, FreeBSD, OpenBSD, NetBSD, MacOSX, Solaris.

With this:

 $ sudo chgrp -R sys /mnt/data/dir
 $ sudo chmod -R g+s /mnt/data/dir
 $ sudo setfacl -R -m g:sys:rwx /mnt/data/dir
 $ sudo setfacl -R -d -m g:sys:rwx /mnt/data/dir

and flavor of this:

 $ sudo adduser user sys

you `user` be able to read/write any file on `/dir`.

Most job may do `setgid` bit but unfortunately you usually have little control on `umask`. So ACL is used to provide complete solution.
