Switching distro without loosing data in /home (lemm.ee)

Is there a way to move distro without loosing data in /home? I am currently running Pop OS and want to move to Nix OS while keeping the data. Normally I could use an external hard drive or my server, but most of my equipment is in storage at the moment. Current partition setup is using LUKS and LVM with ext4. I am guessing there is a way to manipulate the LVM to make it work by adding another partition and installing into it.

I know this is probably a convoluted idea. I am trying to avoid spending money an another external drive.

I moved my home to its own partition a while ago and recently changed my os. It worked well, just had to modify fstab to remap my home drive in the new OS. Not sure if this is what you’re after but I accomplished it al on my main drive by modifying partitions.

Yeah this might be the way. I was hoping I could use something like btrfs subvolumes or some LVM shenanigans to share space with the root. Might not be possible though.

Eveytime I see btrfs, I keep thinking it's pronounced "Better FS", but that's not what it stands for.

I think it stands for b-tree as that's the data structure is uses internally. I could be wrong though.

Yes, B-Tree File System. But Better FS is the dapper Winnie the Poo pronounciation

Why not Butter FS?

Also what's it better than? Than ZFS? Not really. Than BCacheFS? Maybe right now but probably not for long.

Ironic naming.
