   1 F15:
   2
   3 * swap units that are activated by one name but shown in the kernel under another are semi-broken
   4
   5 * NFS, networkmanager ordering issue (PENDING)
   6
   7 * NM should pull in network.target (PENDING)
   8   https://bugzilla.redhat.com/show_bug.cgi?id=692008
   9
  10 * bluetooth should be possible to disable (PENDING)
  11
  12 * 0595f9a1c182a84581749823ef47c5f292e545f9 is borked, freezes shutdown
  13     (path: after installing inotify watches, recheck file again to fix race)
  14
  15 * get writev() /dev/kmsg support into the F15 kernel
  16     https://lkml.org/lkml/2011/4/6/473
  17   patched merged into -mm
  18
  19 * fix sd_is_socket() invocation in dbus
  20
  21 * New CK release, with sysinit.target dropping and TTY loop
  22
  23 * New Avahi package, enable it by default
  24
  25 * make anaconda write timeout=0 for encrypted devices
  26
  27 * Fix assert http://lists.freedesktop.org/archives/systemd-devel/2011-April/001910.html
  28
  29 Features:
  30
  31 * maybe lower default timeout to 2min?
  32
  33 * GC unreferenced jobs (such as .device jobs)
  34
  35 * support wildcard expansion in ListeStream= and friends
  36
  37 * Add ListenSpecial to .socket units for /proc/kmsg and similar friends?
  38
  39 * avoid DefaultStandardOutput=syslog to have any effect on StandardInput=socket services
  40
  41 * use pivot_root on shutdown so that we can unmount the root directory.
  42
  43 * fix alsa mixer restore to not print error when no config is stored
  44
  45 * show enablement status in systemctl status
  46
  47 * write blog stories about:
  48   - enabling dbus services
  49   - status update
  50   - the new configuration files
  51   - you are a distro: why switch?
  52
  53 * maybe add tiny dbus services similar to hostnamed for locale and wallclock/timezone?
  54
  55 * allow port = 0 in .socket units
  56
  57 * rename systemd-logger to systemd-stdio-syslog-bridge
  58
  59 * introduce /usr/lib/binfmt.d/, /usr/lib/tmpfiles.d/
  60
  61 * take BSD file lock on tty devices when using them?
  62
  63 * avoid any flag files, or readahead files in /, we need to support r/o /
  64   or / on tmpfs like Android setups.
  65
  66 * move readahead files into /var, look for them with .path units
  67
  68 * teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
  69
  70 * get process transport into dbus for systemctl -P/-H
  71
  72 * document default dependencies
  73
  74 * support systemd.whitelist=/systemd.blacklist= on the kernel command
  75   line.
  76
  77 * Find a way to replace /var/run, /var/lock directories with
  78   symlinks during an RPM package upgrade (filesystem.rpm or systemd.rpm).
  79   (lua code to create symlinks right away for new installations is in filesytem.rpm now)
  80   We soon want to get rid of var-run.mount var-lock.mount units:
  81     if mountpoint /run ; then
  82           umount /var/run || :
  83     else
  84           mount --move /var/run /run || mount --bind /var/run /run
  85     fi
  86     mv /var/run /var/.run.save
  87     ln -s /run /var/run
  88     echo "R /var/.run.save" > /etc/tmpfiles.d/remove-run-save.conf
  89
  90 * when key file cannot be found, read it from kbd in cryptsetup
  91
  92 * add switch to systemctl to show enabled but not running services. Or
  93   another switch that shows service that have been running since
  94   booting but aren't running anymore.
  95
  96 * reuse mkdtemp namespace dirs in /tmp?
  97
  98 * recreate systemd's D-Bus private socket file on SIGUSR2
  99
 100 * be more specific what failed:
 101     ...
 102     Unmounting file systems.
 103     Not all file systems unmounted, 1 left.
 104     Disabling swaps.
 105     Detaching loop devices.
 106     Detaching DM devices.
 107     Cannot finalize remaining file systems and devices, trying to kill remaining processes.
 108     Unmounting file systems.
 109     Not all file systems unmounted, 1 left.
 110     Cannot finalize remaining file systems and devices, giving up.
 111     ...
 112
 113 * check for compiled-in, but not active selinux, and don't print any warnings
 114   about policy loading. Probably check for available selinux in /proc/filesystems,
 115   and check for active selinux with getcon_raw() == "kernel"
 116
 117 * Support --test based on current system state
 118
 119 * systemctl enable as D-Bus call
 120
 121 * consider services with any kind of link in /etc/systemd/system enabled
 122
 123 * show failure error string in "systemctl status"
 124
 125 * make sure timeouts are applied to Type=oneshot services.
 126
 127 * Maybe implement "systemctl mask" and "systemctl unmask", but not
 128   document it? When doing that add switch to make this temporary by
 129   placing mask links in /dev.
 130
 131 * detect LXC environment
 132
 133 * invoke vhangup() before and after invoking getty
 134     http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=3c95c985fa91ecf6a0e29622bbdd13dcfc5ce9f1
 135
 136 * Maybe store in unit files whether a service should be enabled by default on package installation
 137   (belongs into a distro pattern though, not in an upstream package's service file)
 138
 139 * perhaps add "systemctl reenable" as combination of "systemctl disable" and "systemctl enable"
 140
 141 * need a way to apply mount options of api vfs from systemd unit files
 142   (or some other modern source?) instead of fstab?
 143
 144 * maybe introduce ExecRestartPre=
 145
 146 * figure out what happened to bluez patch
 147
 148 * Patch systemd-fsck to use -C and pass console fd to it
 149
 150 * configurable jitter for timer events
 151
 152 * Support ProcessNeededForShutdown=true to allow stuff like mdmon to
 153   be killed very late after the rootfs is read only? If implement pass
 154   this to shutdown binary via command line argument.
 155
 156 * Integrate "mdadm --wait-clean". Maybe just let SIGTERM to mdmon trigger the
 157   needed action
 158
 159 * dot output for --test showing the 'initial transaction'
 160
 161 * calendar time support in timer, iCalendar semantics for the timer stuff (RFC2445)
 162   - check timerfd() patch: http://lkml.org/lkml/2010/11/23/290
 163
 164 * systemd --user
 165   - get PR_SET_ANCHOR merged: http://lkml.org/lkml/2010/2/2/165
 166
 167 * add VT tracking:
 168   - provide CK functionality
 169   - start getty only when actual vt switch happens (same model as
 170     socket on-demand activation). allocate the next free tty and
 171     start a getty there. this way, pressing alt-f[1-12] will switch
 172     through running X and getty sessions, and any unallocated
 173     activated tty will start a new getty. the hardcoding of
 174     getty[1-6] will entirely go away.
 175   - http://git.kernel.org/?p=linux/kernel/git/gregkh/tty-2.6.git;a=commitdiff;h=fbc92a3455577ab17615cbcb91826399061bd789
 176
 177 * implicitly import "defaults" settings file into all types
 178
 179 * port over to LISTEN_FDS/LISTEN_PID:
 180    - uuidd    HAVEPATCH
 181    - rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
 182    - cups     HAVEPATCH
 183    - postfix, saslauthd
 184    - apache/samba
 185    - libvirtd (/var/run/libvirt/libvirt-sock-ro)
 186    - bluetoothd (/var/run/sdp! @/org/bluez/audio!)
 187    - distccd
 188
 189 * fingerprint.target, wireless.target, gps.target, netdevice.target
 190
 191 * set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
 192
 193 * io priority during initialization
 194
 195 * if a service fails too often, make the service enter failed mode, and the socket, too.
 196
 197 * systemctl list-jobs - show dependencies
 198
 199 * auditd service files
 200
 201 * add systemctl switch to dump transaction without executing it
 202
 203 * suspend, resume support?
 204
 205 * readahead: btrfs/LVM SSD detection
 206
 207 * add separate man page for [Install] settings
 208
 209 * allow runtime changing of log level and target
 210
 211 * drop cap bounding set in readahead and other services
 212
 213 External:
 214
 215 * udisks should not use udisks-part-id, instead use blkid. also not probe /dev/loopxxx
 216
 217 * snd-seq should go, https://bugzilla.redhat.com/show_bug.cgi?id=676095
 218
 219 * gnome-shell python script/glxinfo/is-accelerated must die
 220
 221 * make cryptsetup lower --iter-time
 222
 223 * patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup.
 224
 225 * patch kernel for cpu feature modalias for autoloading aes/kvm/...
 226     http://git.kernel.org/?p=linux/kernel/git/ak/linux-misc-2.6.git;a=shortlog;h=refs/heads/cpuid-match
 227   (Rafael J. Wysocki's sysdev rework is on the way. After that CPUs can be exported a proper bus.)
 228
 229 * procps, psmisc, sysvinit-tools, hostname → util-linux-ng

 250 Regularly:
 251
 252 * look for close() vs. close_nointr() vs. close_nointr_nofail()
 253
 254 * check for strerror(r) instead of strerror(-r)
 255
 256 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
 257
 258 * %m in printf() instead of strerror();
 259
 260 * pahole
 261
 262 * CFLAGS="-Wl,--gc-sections -Wl,--print-gc-sections -ffunction-sections -fdata-sections"
