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). 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.
|
||||
|
||||
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.
|
||||
|
||||

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
