# DeveloperWiki:UsrMove

This article or section is being considered for deletion.

Reason: The move is done long time ago. (Discuss)

This page is for planning.

## Stage 1: Packages with files in /lib

1. rebuild kmod/systemd/udev to read config from both `/lib` and `/usr/lib`, keep `/lib/modules` in place, and accept both `/lib/firmware` and `/usr/lib/firmware` (prefering the latter). Rebuild packages with helpers in `/lib/{udev,systemd}/` at the same time [DONE]
2. rebuild packages with libs, or config files one at a time [DONE]
3. rebuild `/lib/security` [DONE]
4. rebuild `/lib/modules` (linux, kmod, and all other packages which create or package modules) [DONE -- in testing]
5. rebuild glibc with `/lib` symlinked to `/usr/lib`. With `/lib` only having files owned by glibc, this is possible to do in a single transaction.
6. remove any temporary hacks in order to support both `/usr/lib` and `/lib` in udev+kmod+systemd

Steps 1 through 3 are complete. Once step 4 moves from [testing], a final glibc package will reclaim /lib as a symlink instead of a directory.

At each step we must consider how to alert people who have installed third party software.

#### libraries

Plan: Simple rebuild.

    acl
    attr
    bzip2
    cryptsetup
    dmraid
    e2fsprogs
    e4rat
    fuse
    keyutils
    libcap
    libgcrypt
    libgpg-error
    lvm2
    multipath-tools
    nilfs-utils
    nss_ldap
    ntfs-3g_ntfsprogs
    pam
    popt
    procps
    readline
    samba
    sysfsutils
    xfsprogs

#### initcpio

Plan: Simple rebuild.

    archboot
    cryptsetup
    dmraid
    lvm2
    mdadm
    mkinitcpio-nfs-utils
    v86d

#### systemd service files

Plan: Simple rebuild.

    accountsservice
    alsa-utils
    avahi
    backuppc
    bird
    bitlbee
    colord
    consolekit
    dbus-core
    dnsmasq
    libcanberra
    linux-tools
    lm_sensors
    mpd
    netcfg
    networkmanager
    ossp
    pcsclite
    radvd
    rsyslog
    rtkit
    shorewall
    stunnel
    syslog-ng
    wicd

#### udev rules

Plan: Simple rebuild.

    alsa-utils
    bluez
    capi4hylafax
    cdemu-daemon
    colord
    crda
    drbd
    fuse
    gnome-bluetooth
    gpsd
    hplip
    jack
    jack2
    jack2-multilib
    kino
    libffado
    libfprint
    libgphoto2
    lvm2
    mdadm
    media-player-info
    modemmanager
    networkmanager
    ossp
    ozerocdoff
    pulseaudio
    qemu
    qemu-kvm
    rfkill
    sane
    upower
    usbmuxd
    v4l-utils
    virtualbox
    virtualbox-modules
    xf86-input-vmmouse
    xf86-input-wacom

#### modprobe

Plan: Simple rebuild.

    nvidia
    nvidia-lts

#### firmware

Plan: Likely a simple rebuild, as udev has support for both `/lib/firmware` and `/usr/lib/firmware`. However, we should double check that nothing else reads from `/lib/firmware` directly.

    alsa-firmware
    amd-ucode
    bluez-firmware
    intel-ucode
    ipw2100-fw
    ipw2200-fw
    ivtv-utils
    linux-atm
    linux-firmware
    zd1211-firmware

#### security

Plan: Rebuild together.

    consolekit
    ecryptfs-utils
    fprintd
    gnome-keyring
    libcap
    pam
    pam-krb5
    pam_ldap
    pam_mysql
    pam_pwcheck
    samba
    systemd
    thinkfinger
    virtualbox

#### modules

Plan: Simultaneous rebuild, together with kmod+udev. Need to consider custom kernels. Possibly add symlink `/lib/modules` -> `/usr/lib/modules`, if nothing else, this will conflict with custom kernels, making sure nothing is left behind by accident.

    cdfs
    fcpci
    fcpcmcia
    filesystem
    linux
    linux-headers
    linux-lts
    linux-lts-headers
    lirc
    ndiswrapper
    nvidia
    nvidia-lts
    open-vm-tools-modules
    r8168
    r8168-lts
    rt3562sta
    slmodem
    vhba-module
    virtualbox-modules

#### left until the very end

    glibc
    lib32-glibc
