/etc/skel
The /etc/skel directory is quite simple
to setup and use. It provides a way to make sure that all new users on
your LFS system begin with the same settings. The
/etc/skel directory is used by the
/usr/sbin/useradd program.
For more information see man useradd.
To get started create a /etc/skel directory.
Creating the directory as root is the best way to go. Next copy any
files into /etc/skel that you want every new user
to have placed in their home drive. Examples include
.bash_profile, .bashrc,
.bash_logout, dircolors,
.inputrc, and .vimrc.
When creating a new user with
/usr/sbin/useradd use the -m
parameter. For example:
useradd -m -s/bin/bash jwrober
The /usr/sbin/useradd program uses a
collection of default values. It will read them from the
/etc/default/useradd file if it exists. If the
file does not exist, then it uses some internal defaults. They can be
found by running /usr/sbin/useradd -D.
To change these values to something new, create a base
/etc/default/useradd file with the same values as
the output of /usr/sbin/useradd -D. Here is a
sample.
# Begin /etc/default/useradd
GROUP=100
HOME=/home
INACTIVE=-1
EXPIRE=
SHELL=
SKEL=/etc/skel
# End /etc/default/useradd
The only thing missing from the file is a default shell. Add that
by running:
/usr/sbin/useradd -D -s/bin/bash
This will set the SHELL= line to
SHELL=/bin/bash. This makes it even easier to
add new users to your LFS system. The
/usr/sbin/useradd has many parameters that can be
set in the /etc/default/useradd file. See the man
page for more details.
