Manage default home directory permissions with adduser vs. useradd

[Niki Kovacs]

Hi,

I want to set home directory permissions for newly created users to 
0750. Instead of having to manually chmod 0750, I found out I could edit 
this behaviour in /etc/adduser.conf:

DIR_MODE=0750

Now here's a more tricky question. I have to create a series of users 
without shell access. What I'd usually do is something like this:

# useradd -m -g users -s /bin/false -c "Fantasio" fantasio
# useradd -m -g users -s /bin/false -c "Gaston Lagaffe" glagaffe
# useradd -m -g users -s /bin/false -c "Gaston Lagaffe" glagaffe2
# useradd -m -g users -s /bin/false -c "Jeanne Dupont" jdupont
# useradd -m -g users -s /bin/false -c "Bertrand Labévue" blabevue

Unfortunately my DIR_MODE=0750 directive is not operative, and these 
users' home directories get created with default 0755 permissions.

Any idea if there's a secret trick or switch so they're directly created 
with 0750 permissions?

Cheers,

Niki
