I've looked at In OEM Installations can we edit final-user applications setting? and How do I pre-install Ubuntu for someone (OEM install)? The latter offered an amazing guide on how to perform the actual OEM install, but doesn't answer "how can I customise the launcher icons and add a few files to the homedir of the to-be-user".
Neither of them offered the answer I fear.
The OEM setup is fine, works well too. I just can't get a few dot files made for the to-be-user. One is a config file for our VPN client (server name and the likes) and the other are config files for our vmware view client. It's for a-technical users, hence the OEM option being so nice.
I assumed at first, since you can change "settings", I'd add them as oem user, but since its homedir gets removed - no dice.
I tried via upstart and init.d several times but I couldn't get it to execute. I also tried to use the System Prefs > Startup Applications. I've tried looking at oem-config/late_command but it's beyond me. I am sorry.
I've been looking for the answer for over 2 days now, tried everything I could find - but I've come up empty handed.
I forgot to mention: My attempts (and a few versions for various alternatives to the OEM install) can be found here https://gist.github.com/moonwitch
