William Carroll 52d284f59d Remove assertions that prelude/executable-exists?
I'm in the midst of transitioning onto a few new tools.

My previous workflow just used `nix-env` to install *some* packages. I didn't
have a prescribed methodology for which packages I would install using `nix-env`
and which ones I would install using `sudo apt-get install`. Sometimes if a
package would be available in my aptitude repositories, I'd use that; other
times when it wasn't available I'd use `nix-env`. One complication about being
on gLinux intead of NixOS is that some packages (e.g. nixpkgs.terminator) is
available via `nix-env -iA nixpkgs.terminator`, but the installation won't
actually run on my gLinux. In these instances, I would install terminator from
the aptitude repositories.

Then @tazjin introduced me to his Emacs configuration that he builds using
Nix. What appealed to me about his built Emacs is that it worked as expected on
either a NixOS machine and on gLinux (and presumably on other non-NixOS machines
as well).

A setup towards which I'm working is to own one or a few NixOS machines whose
configurations are entirely managed with Nix. On devices like my work machines,
which cannot run NixOS, I can build as much of the software that I need using
Nix and attempt to minimize the ad hoc configuration either with shell scripts,
python, golang, or more Nix code... it's clear that I still don't have a clear
idea of how that part will work.

For now, I'm adopting nix, nix-env, lorri, direnv, and weening off of aptitude
as much as I can. Things are a bit messy, but my general trend feels
positive. Stay tuned for more updates.
