Problem with usermod

[wolfikk2]

Hello, can somebody explain me this problem?
I've created a user with command:

$this->bbcode_second_pass_code('', 'sudo useradd -g xyz -s /sbin/nologin -d /home/xyz xyz')

but when I tried to modify that user like this:

$this->bbcode_second_pass_code('', 'sudo usermod -R /home/xyz xyz')

then bash says:

$this->bbcode_second_pass_code('', 'usermod: user 'xyz' does not exist')

did you prepare your system for a chroot with the "-R" option? I think if you switch to /home/xyz as the new filesystem-root, you have to install the necessary configuration files in that directory. If the filesystem is empty at this place, the command won't find files like /etc/passwd and therefore will not find the userid.
