Custom ISO With Post Installation Scripts

Dear All

I have been working on a custom ISO with kickstart and a couple of post
installation scripts and would like to have the script run before the
login prompt.

The custom ISO works; however, the scripts fails because some of the
services, e.g. mariadb does not start before the server installation
has been completed and rebooted; therefore, I have been putting the
scripts in /etc/profile.d/ and after logging in the scripts will
execute and upon completion of the script will be deleted from

DuckDuckGo suggested that I copy the script to /etc/rc.d/rc.local and
make it executable; however, I have tried that a few times and the
script simply does not execute.

Below is an excerpt from the ks.cfg.

export SRCDIR="/run/install/repo"
export DSTDIR="/mnt/sysimage"

# copy scripts to the destintion of the server
cp -v $SRCDIR/postinstall/

# Make scripts executable
chmod +x $DSTDIR/etc/rc.d/

Since this is a ISO for a community project, don't think that tools
such as Ansible, Chef, Puppet, etc. will work here.

Also, it is a one time execution; therefore, I did not consider using
systemd because the goal would be to have visibility while the script
is running just as I see after I login; however, just need the script
to be executed after the OS was installed and restarted and before the
login prompt.

All suggestions are welcome.

Thanks in advance.

are you sure about this line? rc.local must be a file, not a directory.

best regards

That was a typo on the email

cp -v $SRCDIR/postinstall/ $DSTDIR/etc/rc.d/rc.local

# Make scripts executable
chmod +x $DSTDIR/etc/rc.d/rc.local
