This question is similar but it seems to deal with a /home partition on same drive as / partition so not sure if answer would be the same as setup I am proposing.
I am hoping to set up my new laptop with / on a ssd and /home on a hdd. Ubuntu will be the only OS installed. I was just planning to use the system encryption in the installation process.
I note that in the answer to this question it is stated that
With LUKS your entire installation (except /boot) will be encrypted, including your home directory.
I was not planning to use the separate /home encryption as I'll be the only user on the computer.
So if I select the LUKS encryption will this encrypt my /home partition on the separate hdd or do I need to customise my install in some way to accommodate this?
