When I usually install ubuntu from scratch, I configure my own custom partition layout during installation setup (e.g /var/log, /home, and etc. on separate partitions), which is much easier than changing the partitions after installation.
This is my first time installing ubuntu on raspberry pi (ver 4). and I would like to follow my usual partition layout. However from all the guides I found, I can only dump the image on to an SD, and have no way of setting the partitions before hand. (I also usually choose to use LVM, I don't know if it's used by default- but that will be much harder to change)
What are my options here?
