When you have a notebook install, you are locked into the drive you have and whatever you did on the partitioning, you are stuck with, for the most part. No adding a new drive with additional partitions.
Exactly, that was my main point: that YOU get more flexibilty with GPT on an one-disk only box - maybe with the cost of new install AND re-partition ! - The time you need to spent now is the time you save in the future - in my view -
I originally deleted the default LVM setup and then created the ext4 partitions you see in the original post. The Fedora installer created those partitions. It was my oversight in not making swap larger in the 1st place; I was controling the install knobs.
I never use "automatic partitioning", cause I need to leave my /home un-touched. Otherwise you get LVM (still valid ?) or msdos partition scheme. In your current case LVM had been a win too, it also bring flexibility regarding re-partioning/re-sizing
I know/have learned if you don't start the installer without parameter inst.gpt (?) and choose manual partitioning you get the current partition scheme.
Maybe one should think about to make inst.gpt a default boot parameter for the installer ?
