One argument for the change is that it would be easier to do basic partition management after the install, after months of years, the partition sizes could need changes
I’m thinking about resizing graphically with Gparted. Thus I would like to avoid encrypted installs to have an LVM layer.
This is especially important at install parties because most of my colleagues aren’t experienced enough to resize an LVM setup with the command line. And even for me, it’s more time consuming and error prone. Like forgeting to tell LVM to resize the partition in the logicial volume an thus eating it’s data.
