It very much does matter whether you use a swap file or partition in |
| 11 |
practice. I've just been reading right now a discussion about systemd |
| 12 |
logging and hibernation, and how btrfs handles swap files. It sounds nasty. |

If you have a swap file, linux creates an immutable file then uses |
| 15 |
direct disk i/o. There's a LOT of unnecessary crap there that could go |
| 16 |
wrong. Just avoid all that trouble and give yourself a decent swap |
| 17 |
partition. (And if you're running btrfs, a lot of this sounds |
| 18 |
experimental and dangerous ...) |
