it has taken time but I have autoinstall working. I am converting from CentOS 7 kickstart. I need to install (remotely) 20.04 on machines with 2G Ram. No more ram can be installed as they are remote.
I log into the machine - edit the 40_custom file, download the vmlinuz and initrd files from casper - re-run grub2-mkconfig for CentOS 7 and all - when it reboots its starts installing 20.04. however - it runs out of ram in 2G !
my kernel line is this: ramdisk_size=1500000 root=/dev/ram0 fsck.mode=skip autoinstall splash ‘ds=nocloud-net;s=http://MyIP/autoinstall/’ ip=dhcp ‘url=http://releases.ubuntu.com/focal/latest-live-server-amd64.iso’
This starts to work, boots, downloads the iso, but then gets a out of memory error and goes to the welcome screen.
How can I remotely install 20.04 in 2G ram ?
