This is achieved by having multiple lines per storage file, one for each user (if the feature is enabled); each of these
lines has the same format as would be the case for the userless authentication, except that they are prepended with a
SHA-512 of the user's id.
'YubiKey Integration for Full Disk Encryption Pre-Boot Authentication (Copyright) Yubico, 2011 Version: 1.1'.
Used binaries:
* uuidgen - for generation of random sequence numbers
* ykchalresp - for challenging a Yubikey
* ykinfo - to check if a Yubikey is plugged in at boot (fallback to passphrase authentication otherwise)
* openssl - for calculation of SHA-1, HMAC-SHA-1, as well as AES-256-CTR (de/en)cryption
Main differences to the specification mentioned above:
* No user management (yet), only one password+yubikey per LUKS device
* SHA-512 instead of CRC-16 for checksum
Main differences to the previous implementation:
* Instead of changing the key slot of the LUKS device each boot,
the actual key for the LUKS device will be encrypted itself
* Since the response for the new challenge is now calculated
locally with openssl, the MITM-USB-attack with which previously
an attacker could obtain the new response (that was used as the new
encryption key for the LUKS device) by listening to the
Yubikey has ideally become useless (as long as uuidgen can
successfuly generate new random sequence numbers).
Remarks:
* This is not downwards compatible to the previous implementation
This will allow overriding package-provided units, or overriding only a
specific instance of a unit template.

Includes configuration option for the threshold beneath which to refill
the entropy pool - defaults to 1024 bits as this is the number used in
other distro's existing service files I looked at.
With kmscon, it is now possible to have a system without X that still
needs the mesa setup in /run/opengl-driver

This required some changes to systemd unit handling:
* Add an option to specify that a unit is just a symlink
* Allow specified units to overwrite systemd-provided ones
* Have gettys.target require autovt@1.service instead of getty@1.service

Now that Java is happy with our /etc/localtime, there is no reason to
set $TZ anymore. (See 945849b86f, 279248f6c5, 1b5e860f65607b4cc7de4b6b5db95460cf144526.)
Fixes#1463.
Some programs (notably the Java Runtime Environment) expect to be able
to extract the name of the time zone from the target of the
/etc/localtime symlink. That doesn't work if /etc/localtime is a
symlink to /etc/static/localtime. So make it a direct symlink.
This is a second attempt at unifying the generic and manual-config
kernel builds (see #412 for the last time).
The set of working kernel packages is a superset of those that work on
master, and as the only objection last time was the size of the $dev
closure and now both $out and $dev combined are 20M smaller than $out on
master (see message for ac2035287f), this
should be unobjectionable.

In most cases, this just meant changing kernelDev (now removed from
linuxPackagesFor) to kernel.dev. Some packages needed more work (though
whether that was because of my changes or because they were already
broken, I'm not sure). Specifics:
* psmouse-alps builds on 3.4 but not 3.10, as noted in the comments that
were already there
* blcr builds on 3.4 but not 3.10, as noted in comments that were
already there
* open-iscsi, ati-drivers, wis-go7007, and openafsClient don't build on
3.4 or 3.10 on this branch or on master, so they're marked broken
* A version-specific kernelHeaders package was added
The following packages were removed:
* atheros/madwifi is superceded by official ath*k modules
* aufs is no longer used by any of our kernels
* broadcom-sta v6 (which was already packaged) replaces broadcom-sta
* exmap has not been updated since 2011 and doesn't build
* iscis-target has not been updated since 2010 and doesn't build
* iwlwifi is part of mainline now and doesn't build
* nivida-x11-legacy-96 hasn't been updated since 2008 and doesn't build
Everything not specifically mentioned above builds successfully on 3.10.
I haven't yet tested on 3.4, but will before opening a pull request.

The difference between xsession and xprofile is that xsession is exec'd and xprofile is sourced.
So with xprofile all commands after sourcing will still be exectued. This allows for instance
autostarting of applications while configuring the start of a window manager via configuration.nix.
This patch adds support for the creations of new bond devices, aggregate
pipes of physical devices for extra throughput or failover.
Additionally, add better correction at the startup of a bridge
of vlan interface (delete old, stale interfaces).
The redshift service stops working after some time (the program exits
after some hours/days). It looks like these exits are related to calls
to xrandr (for multiple displays) or suspend-to-ram.

PR #1366
The previous windowManager.xmonad option only starts xmonad and
doesn't make ghc available. This assumes that the user has GHC with
access to the xmonad package in his PATH when using xmonad.
Xmonad in Nix is now patched to accept the XMONAD_{GHC,XMESSAGE}
environment variables which define the path to either ghc or xmessage.
These are set automatically when using xmonad through
windowManager.xmonad.
My (or specific: @aristidb and my) changes make it possible to use
Xmonad without adding GHC to any profile. This is useful if you want
to add a different GHC to your profile.
This commit introduces some options:
- xmonad.haskellPackages: Controls which Haskell package set & GHC set
is used to (re)build Xmonad
- xmonad.extraPackages: Function returning a list of additional
packages to make available to GHC when rebuilding Xmonad
- xmonad.enableContribExtras: Boolean option to build xmonadContrib
and xmonadExtras.
