As asked for by jrollins on irc, more info on my build environment:

I use nixos [1] which uses the nix package manager [2] and nixpkgs
package collection [3].

nix and nixpkgs can be used independent of nixos on top of many
operating systems [4]. Packages installed via nix are fully isolated
From the rest of the system.

Package builds are described via nix expressions (see example for
notmuch attached). The build happens fully isolated.

Some big differences of nixos to other systems:
- no /usr, instead profiles (system, default, user)
- everything in /nix/store and linked into profiles
- atomic changes
- easy rollback to old version
- each profile fully isolated of other profiles
- possible to have dedicated profiles, i.e. isolated environments, for
development

For more info, see [1], freenode #nixos and I'm happy to answer
questions.

regards
florian
