I am trying to upgrade (or "lustrate" as the NixOS people say) a Debian system running on a virtual server, roughly following existing guides by wingo and ng0. I documented how I went about this here: https://gist.github.com/jboynyc/ef312a686749de693dddc4f3a657a919
As I write in that document, initialization of GuixSD over the Debian system seems to work, and I am even able to log into the system with ssh using the provided key. Once I start doing something with the system, however, I start getting strange "No such file or directory" errors about the guix command, sshd, and any other binary I attempt to run. Booting from a live CD and poking around on the disk shows that files are in fact present in the file system. I have re-run the install at least five times, and each time I end up with the system in an unusable state. Any ideas what might be happening?
