Re: Multi-user and shared directories

"umod 002" -> "umask 002"

"you can only have one group to a file/directory" : it isn't very right,
at least ext2, ext3 and xfs filesystems supports POSIX Access Control Lists
(ACL - see "man acl", "man getfacl","man setfacl") and is possible set
different access rights (read, write, search/execute) on directories/files
for different users and different groups. And on directories is possible set
default ACL, again for different users and/or different groups, and new
objects inherits default ACL of the containing directory as its access ACL.
