This directory contains nix integration for building and testing LVM2 in various

virtual machine configurations. The *.nix files are written in the nix

declarative language (see http://nixos.org/nix).

There are two basic use-cases for this integration. First, a hydra instance (see

http://divine.fi.muni.cz/hydra/project/lvm2 and

http://divine.fi.muni.cz/~xrockai/lvm-testmatrix.html) builds and tests LVM in

all the configurations described in default.nix after every push to the git

repository. Second, any nix-enabled system can very closely reproduce any of

those test scenarios using the "build.sh" script and an appropriate checkout of

"nixpkgs" (cf. http://nixos.org/nixpkgs).

(The rest of this document is TODO.)
