Bcachefs Merged into the Linux 6.7 Kernel

Can you not just place the swapfile inside of another subvolume? Since subvolumes are not included in snapshots. There's generally a bunch of stuff in /var that you don't want to include in snapshots, too, so it's not like putting the swapfile inside of a subvolume is an exotic task.

I guess so, I just didn't know when I created the swapfile and was surprised later when I tried to create a snapshot.

Be careful, just like disk images, you probably don't want to place swapfiles on a CoW filesystem.

You can mark individual files as No_COW in btrfs, and No_COW + preallocation is a requirement for swapfiles anyway due to how the swap subsystem works.
