* Scripts to set up and run the absolute minimal pure Nix environment; that is, an operating system environment in which there is (essentially) only a store. The script `make-disk.sh' creates an ext2 disk image, creates a Nix store in it, and copies the closure of the bash package (from nixpkgs) to it. The script `run.sh' then starts bash in a UML virtual machine. The contents of the image after creation look like this: $ ls -l drwxr-xr-x 2 root root 1024 2004-02-14 19:13 dev lrwxrwxrwx 1 root root 61 2004-02-14 23:34 init -> /nix/store/e40873ece7a010752ad72b4262b23d28-bash-2.05b/bin/sh drwx------ 2 root root 12288 2004-02-14 19:13 lost+found drwxr-xr-x 4 root root 1024 2004-02-14 19:13 nix drwxr-xr-x 2 root root 1024 2004-02-14 19:13 proc drwxrwxrwt 2 root root 1024 2004-02-14 19:13 tmp The next step is to add all the other stuff that goes into a working system (coreutils, etc.). BTW, if you don't have `ls' you can still list directories by doing `echo *' :-) Nix itself should also be Nixified so that it can be put into the store. svn path=/nixu/trunk/; revision=783

copy nixpkgs, so it reflects what was built. This code uses a simple "cp -a" so there is a race condition (nixpkgs being altered after the build). However, with a bit of care and "policy" this should work ;-) Also push all packages we want to push at once. svn path=/nixu/trunk/; revision=3292
