For home use, this completely makes sense and I think that there are a
few things that I have figured out that make life simpler for me. They
are probably in some book somewhere.

- from the outset, plan a common group of users with the most general
ambitions and have all users belong to that group as primary group.
- it keeps /home fairly neat as I tend to create user profiles for kids,
friends, anyone who is going to sit in front of one of my computers.
- don't just create users home directories in /home, make a directory
called /home/users and create users home directories there. Why?
  - I put mounts in /home such as other nfs/smb servers and 
    access them fairly easily
  - I can change my mind and mount other nfs server home 
    directories easily. I actually have a scenario where I have
    ldap providing authentication for users on a few systems
    and instead of creating a users $HOME on each system, I create
    the nfs mount and their home directory is located in the same
    path (and with the same uid). Yes, I know that it's not generally
    a good idea to have home directories on nfs mounts but for
    light duty, it's workable.
  - I can relocate other data directories such as apache's there
  - I can locate 'shared' directories there easily.
  - I can use the same users home directory for posix user and samba
    user without worrying about mucking the privileges of /home 
    (not a good idea). This allows netscape/mozilla roaming
    profile between various computers/OS's
  - I can change user defaults in /etc/default/useradd (Red Hat)

i.e.:
groupadd users-all
useradd -g users-all craig -d /home/users -n
