Proposal: add setup_user option or script

[Jesse G]

I'm proposing an option to chroot_setup (or perhaps a separate script) that would prepare a chroot for a particular user by performing the following steps (written in pseudoscript, with $USER being the given user):

mkdir -p $CHROOT_DIR/home/$USER
chown -R $USER  $CHROOT_DIR/home/$USER
system -kpieb "CHGUSRPRF USRPRF($USER) HOMEDIR('$CHROOT_DIR/./home/$USER')
cp ~/.profile $CHROOT_DIR/home/$USER
cp ~/.bash_profile $CHROOT_DIR/home/$USER

Here's a sample of what I've been using. Does a number of defaults. It is done from a .lst file. I am split on whether to continue using .lst for custom stuff like this or to switch to doing .sh files.

Obviously this would require global variables to be passed. (i.e. chroot_setup -g myuser=AARON -g mydir=/QOpenSys/mychroot1 /QOpenSys/mychroot1 /path/to/add_user.lst).

Another feature I think we should add is to alter the prompt (via PS1 alteration, seen below) to denote whether you're in a chroot or not. Currently I only display the user, machine and current directory.

:mkdir

/QOpenSys/etc/ssh

:sh
ssh-keygen -q -N '' -C '' -f mydir/home/myuser/.ssh/id_rsa

touch mydir/home/myuser/.ssh/known_hosts
printf "Host *\nIdentityFile /home/myuser/.ssh/id_rsa\nUserKnownHostsFile /home/myuser/.ssh/known_hosts\n\n" > mydir/QOpenSys/etc/ssh/ssh_config

echo "TERM=xterm" >> mydir/home/myuser/.profile
echo "umask go=" >> mydir/home/myuser/.profile
echo 'export PATH=/QOpenSys/pkgs/bin:$PATH' >> mydir/home/myuser/.profile

echo "alias ls='ls -F --color=auto'" >> mydir/home/myuser/.bashrc
