Hmmm, I do think that this does not really answer the question "Why" here. Consider you have three users: - stephen - ralf - martin Now stephen wants to give ralf, but not martin read access to his home directory. Nothing easier than that with user group system: chmod g=rx,o= /home/stephen adduser ralf stephen Done. Granted this can be done with ACLs as well, but without ACL it would not be possible if all users were in the same group. OTOH with all users in the same group its easier to create a group directory. > It's your freedom to setup your Linux as needed.
