In my experience it's very rare that root would need to do it. If root
is reserved mostly for doing those dirty sys-admin tasks then it needn't
worry much about file sharing with those pesky users, so far as to say
the usual root-shared files (libraries, executables, /usr/share, etc.)
Usually it's the case that a) Users need to share a file with root or b)
users need to share files with each other. In the former case it's
trivial. All your file are belong to root. In the latter case, there
are varying methods of doing it, depending on the desired effect. If
it's just a one-time thing usually you'll deposit a file in /tmp
or /var/tmp and share it there. Another way is to consider a group of
users are working a project. Call it project1.
Create a group called project1:
$ groupadd project1
Add users to the group:
$ gpasswd -a user1 project1
$ gpasswd -a user2 project1
$ gpasswd -a user3 project1
Create a shared directory for the group:
$ mkdir -p /usr/local/projects/project1
$ chgrp project1 /usr/local/projects/project1
$ chmod g+s /usr/local/projects/project1
Then, depending on your user's umask's they should all have access to
files created in that directory.
You could also use ACLs but you need make sure your kernel and toolset
is configured for it.
But I can't remember the last time i needed to share anything in /root
with a non-root user.
