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). 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.
|
|
|
|
/nix/var/nix/profiles
|
|
/var/nix/profiles
