Hi,

This patchset adds new record types swap-partition and swap-file, to be used in the swap-devices field of operating-system. These support dependencies on mapped-device and file-system objects respectively, as well as swapon flags. I pulled those from GNU libc, and in the manual I refer to 'man 2 swapon' for the description of these flags. Support for the old style is kept for now, but I added deprecation warnings.

This works well on my laptop, whereas my swap file used to never be swapon on boot because it wasn't available yet (on BTRFS on LUKS). I don't have a swap partition lying around though so testers welcome!

I hope this can make it in time for the core-updates-frozen merge. I also plan to add swap file hibernation support eventually, where the file offsets are automatically determined by guix (or we could even write our own suspend/resume script in guile, see https://www.kernel.org/doc/html/latest/power/userland-swsusp.html).
