Every Nixy solution I could find or conceive had too many points spread across
these various facets:
- Flimsy (emacsWithPackagesFromUsePackage)
- Inelegant (builtins.exec, manual listings)
- Inflexible (emacsWithPackagesFromUsePackage)
- Otherwise unergonomic (everything }:D)
Straight.el is sufficiently declarative, flexible, and Nix-friendly without
blindly bowing down to the imperialist NixOS user. Now, Convenience and
ergonomics shan't be forsaken for the dogma that is total Nixation.
I had to disable initrd's systemd stuff. I just /couldn't/ get a rollback
service working; believe me, not for a lack of effort! I've been working on
this on-and-off for a month or two now.
