Debian/Ubuntu’s Preseed is not the easiest thing to understand. Having used Red Hat/CentOS Kickstart Profiles for so long, trying to setup a Preseed file for the first time was an extremely uninviting process.
Ubuntu has support for using Kickstart Profiles, but it isn’t as full featured as Preseed, and I have encountered plenty of edge cases where Kickstart Profiles do not work for provisioning Ubuntu systems.
I currently spend a lot more time with Ubuntu than Red Hat or CentOS, so all I can do is try to better understand Preseed.
