That’s not the question that needs to be answered, first you must allocate enough space for you system
partition, and whatever other system related partitions that you want to use, var
, temp
, swap
, you get the gist, then whatever space you have left is your home
partition. This scenario being a default personal use desktop ofc.
If this is going to be a BTRFS system then it also doesn’t matter since sub volumes share the total space available dynamically.
Also if this is a modern hardware consider not having a swap partition and instead use ZRAM.
It’s fine. “Only 27GB” is hardly too small for the system, even a bloated system wouldn’t take that much space.
But if you must have a larger partition I think a reinstall would be easier, resize the partition is possible but because of the encryption not a straight forward thing. I wouldn’t bother really.
