modules/nixos: add disko-zfs-swap #1252
Conversation

Should I test installing this on build01? |
No, I'll do it myself. I would appreciate a response to #1207 (comment). |
Without trying it myself, I can't tell. |

@Mic92 I tried this on build01. Installed, booted, another zfs import error. Is there some sort of weird systemd-boot / zfs problem? |
No. I use systemd-boot in many places. Only thing I can think of is that the pool is not exported correctly. In nixos-anywhere we do this: https://github.com/nix-community/nixos-anywhere/blob/f99d120b3788a286989db4e592a698f5d310d2f6/src/nixos-anywhere.sh#L516 |

I disabled uefi on build03 so now it is the same as 01 and 02. |

Doesn't this suffer from the same issue that we also have with swap files on zfs filesystems? Also now that zfs has proper direct I/O maybe this is not an issue? https://github.com/openzfs/zfs/releases/tag/zfs-2.3.0-rc1

zvol is used as an example in the zram-generator docs so I'm assuming that it works.
