In light of recent automation trends, I would like to be able to fully automate an install of Ubuntu. My my first problem was auto selection of the bootif with multiple NICs break Ubuntu/Debians preseed very badly. I ended up fixing that with the following kernel options.
ksdevice=bootif netcfg/link_wait_timeout=10 netcfg/dhcp_timeout=60 netcfg/choose_interface=auto auto-install/enable=true(Hope that part helps someone we work mostly with RedHat distros so I spent a good part of a month going from zero to get to this point for Ubuntu… among other projects.)
That being said. I was able to fully automate the install!!! YAY… except… the new issue is that when the system restarted I had no display.
With some research I discovered that it is likely a hardware/kernel driver module unavailability issue for the graphics… since this is a server graphics are not my concern at the moment. I chose to insert the
debian-installer/add-kernel-opts string nomodesetoption to offset this.Unfortunately this didn’t work. I further discovered that while this did not work it was because I still have the “default”
splashandquietkernel options being enabled.holding shift during boot allows me to get into the grub boot loader and change this temporarily. As such I was able to verify that removing these two options does indeed fix the issue.
Sorry for the long winded wind-up, essentially my question is how do I remove the default kernel options from being installed on an Ubuntu system during preseed when I cannot run scripts against the
/target/system. ??
Answer
With preseed, you can execute a late_command that will be executed at the end of the installation process.
d-i preseed/late_command string in-target wget -P /tmp/ $server/script.sh; in-target chmod $+x /tmp/script.sh; in-target /tmp/script.sh
Basically, you just have to modify the kernel options of the target system.
Hope it helped !
