When logged in as user root, making a
single mistake can damage or destroy a system. Therefore, we
recommend building the packages as an unprivileged user. You could
use your own user name, but to make it easier to set up a clean work
environment, create a new user called clfs as a member of a new group (also named
clfs) and use this user during the
installation process. As root, issue
the following commands to add the new user:
groupadd clfs useradd -s /bin/bash -g clfs -d /home/clfs clfs mkdir -pv /home/clfs chown -v clfs:clfs /home/clfs
The meaning of the command line options:
-s
/bin/bash
This makes bash
the default shell for user clfs.
-g
clfs
This option adds user clfs to
group clfs.
clfs
This is the actual name for the created group and user.
To log in as clfs (as opposed to
switching to user clfs when logged in
as root, which does not require the
clfs user to have a password), give
clfs a password:
passwd clfs
Grant clfs full access to
${CLFS} by making clfs the directory's owner:
chown -Rv clfs ${CLFS}
Next, login as user clfs. This can be
done via a virtual console, through a display manager, or with the
following substitute user command:
su - clfs
The “-” instructs su to start a login shell as
opposed to a non-login shell. The difference between these two types
of shells can be found in detail in bash(1) and info
bash.
