Many NixOS configurations and Nix packages now use significantly less disk
|
|
space, thanks to the
|
|
<link
|
|
xlink:href="https://github.com/NixOS/nixpkgs/issues/7117">extensive
|
|
work on closure size reduction</link>. For example, the closure size of a
|
|
minimal NixOS container went down from ~424 MiB in 16.03 to ~212 MiB in
|
|
16.09, while the closure size of Firefox went from ~651 MiB to ~259 MiB.

A large number of packages have been converted to use the multiple outputs
|
|
feature of Nix to greatly reduce the amount of required disk space, as
|
|
mentioned above. This may require changes to any custom packages to make
|
|
them build again; see the relevant chapter in the Nixpkgs manual for more
|
|
information. (Additional caveat to packagers: some packaging conventions
|
|
related to multiple-output packages

Previous versions of Nixpkgs had support for all versions of the LTS
|
|
Haskell package set. That support has been dropped. The previously provided
|
|
<literal>haskell.packages.lts-x_y</literal> package sets still exist in
|
|
name to aviod breaking user code, but these package sets don't actually
|
|
contain the versions mandated by the corresponding LTS release. Instead,
|
|
our package set it loosely based on the latest available LTS release, i.e.
|
|
LTS 7.x at the time of this writing. New releases of NixOS and Nixpkgs will
|
|
drop those old names entirely.

Special filesystems, like <literal>/proc</literal>, <literal>/run</literal>

and others, now have the same mount options as recommended by systemd and

are unified across different places in NixOS. Mount options are updated

during <command>nixos-rebuild switch</command> if possible. One benefit

from this is improved security — most such filesystems are now mounted

with <literal>noexec</literal>, <literal>nodev</literal> and/or

|
<literal>nosuid</literal> options.
