Well having a dedicated /home
partition is the very minimum and pretty much default.
If you are interested in having a backup/restore solution for your system you are looking for BTRFS
which uses sub volumes instead of primary partitions and is compatible with snapshot tools, those tools being Timeshift and Snapper.
I do think Snapper is the superior solution however it’s also more complex to set up and requires significantly more prep work. Imo totally worth it.
I currently use it on my main machine Debian with BTRFS and Snapper and couldn’t be happier.
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 yourhome
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.
