-nix (functional package manager)
-
-Nix is a purely functional package manager. This means that it treats packages
-like values in purely functional programming languages such as Haskell -- they
-are built by functions that don't have side-effects, and they never change
-after they have been built. Nix stores packages in the Nix store, usually the
-directory /nix/store, where each package has its own unique subdirectory such
-as
-
- /nix/store/b6gvzjyb2pg0kjfwrjmg1vfhh54ad73z-firefox-33.1/
-
-where b6gvzjyb2pg0... is a unique identifier for the package that captures all
-its dependencies (it's a cryptographic hash of the package's build dependency
-graph).
-
-Nix may be run in single or multi-user mode (which requires the nix-daemon).
-The following sets up multi-user mode.
-
-To have the nix daemon start and stop with your host, add to /etc/rc.d/rc.local:
-
- if [ -x /etc/rc.d/rc.nix ]; then
- /etc/rc.d/rc.nix start
- fi
-
-and to /etc/rc.d/rc.local_shutdown (creating it if needed):
-
- if [ -x /etc/rc.d/rc.nix ]; then
- /etc/rc.d/rc.nix stop
- fi
-
-The daemon requires users for building the nix packages, which should be added
-under the 'nixbld' group.
-
- # groupadd -g 314 nixbld
- # for n in $(seq 1 10); do useradd -c "Nix build user $n" \
- # -d /var/empty -g nixbld -G nixbld -M -N -r -s "$(which nologin)" \
- # nixbld$n; done
-
-Restricting access to the daemon is acheived by setting file permissions for
-the daemon's socket's folder.
-
- # groupadd nix-users
- # chgrp nix-users /nix/var/nix/daemon-socket
- # chmod ug=rwx,o= /nix/var/nix/daemon-socket
-
-Correct permissions must also be set for the following profile directories to
-give users access.
-
- # mkdir -p /nix/var/nix/profiles/per-user
- # chgrp nix-users /nix/var/nix/profiles/per-user
- # chmod go+wt /nix/var/nix/profiles/per-user
-
- # mkdir -p /nix/var/nix/gcroots/per-user
- # chgrp nix-users /nix/var/nix/gcroots/per-user
- # chmod go+wt /nix/var/nix/gcroots/per-user
-
-For setup a user to use nix, add him to the nix-users group and load these
-lines on login (via $HOME/.profile):
-
- export NIX_REMOTE=daemon
- source /etc/profile.d/nix.sh
