3 | CHANGES WITH 41: |
4 | * The systemd binary is installed /usr/lib/systemd/systemd now; | |
5 | An existing /sbin/init symlink needs to be adapted with the | |
6 | package update. | |
7 | ||
b13df964 LP |
8 | * The code that loads kernel modules has been ported to invoke |
9 | libkmod directly, instead of modprobe. This means we do not | |
10 | support systems with module-init-tools anymore. | |
11 | ||
12 | * Watchdog support is now already useful, but still not | |
13 | complete. | |
14 | ||
15 | * A new kernel command line option systemd.setenv= is | |
16 | understood to set system wide environment variables | |
17 | dynamically at boot. | |

23 | CHANGES WITH 40: |
24 | * This is mostly a bugfix release | |
25 | ||
26 | * We now expose the reason why a service failed in the | |
27 | "Result" D-Bus property. | |
28 | ||
29 | * Rudimentary service watchdog support (will be completed over | |
30 | the next few releases.) | |
31 | ||
32 | * When systemd forks off in order execute some service we will | |
33 | now immediately changes its argv[0] to reflect which process | |
34 | it will execute. This is useful to minimize the time window | |
35 | with a generic argv[0], which makes bootcharts more useful | |

41 | CHANGES WITH 39: |
42 | * This is mostly a test release, but incorporates many | |
43 | bugfixes. | |
44 | ||
45 | * New systemd-cgtop tool to show control groups by their | |
46 | resource usage. | |
47 | ||
48 | * Linking against libacl for ACLs is optional again. If | |
49 | disabled, support tracking device access for active logins | |
50 | goes becomes unavailable, and so does access to the user | |
51 | journals by the respective users. | |
52 | ||
53 | * If a group "adm" exists, journal files are automatically | |
54 | owned by them, thus allow members of this group full access | |
55 | to the system journal as well as all user journals. | |
56 | ||
57 | * The journal now stores the SELinux context of the logging | |
58 | client for all entries. | |
59 | ||
60 | * Add C++ inclusion guards to all public headers | |
61 | ||
62 | * New output mode "cat" in the journal to print only text | |
63 | messages, without any meta data like date or time. | |
64 | ||
65 | * Include tiny X server wrapper as a temporary stop-gap to | |
66 | teach XOrg udev display enumeration. This is used by display | |
67 | managers such as gdm, and will go away as soon as XOrg | |
68 | learned native udev hotplugging for display devices. | |
69 | ||
70 | * Add new systemd-cat tool for executing arbitrary programs | |
71 | with STDERR/STDOUT connected to the journal. Can also act as | |
72 | BSD logger replacement, and does so by default. | |
73 | ||
74 | * Optionally store all locally generated coredumps in the | |
75 | journal along with meta data. | |
76 | ||
77 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
78 | writing short strings to files (for usage for /sys), and for | |
79 | creating symlinks, character and block device nodes. | |
80 | ||
81 | * New unit file option ControlGroupPersistent= to make cgroups | |
82 | persistent, following the mechanisms outlined in | |
83 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
84 | ||
85 | * Support multiple local RTCs in a sane way | |
86 | ||
87 | * No longer monopolize IO when replaying readahead data on | |
88 | rotating disks, since we might starve non-file-system IO to | |
89 | death, since fanotify() will not see accesses done by blkid, | |
90 | or fsck. | |
91 | ||
92 | * Don't show kernel threads in systemd-cgls anymore, unless | |
93 | requested with new -k switch. | |

98 | CHANGES WITH 38: | |
99 | * This is mostly a test release, but incorporates many | |
100 | bugfixes. | |
101 | ||
102 | * The git repository moved to: | |
103 | git://anongit.freedesktop.org/systemd/systemd | |
104 | ssh://git.freedesktop.org/git/systemd/systemd | |
105 | ||
106 | * First release with the journal | |
107 | http://0pointer.de/blog/projects/the-journal.html | |
108 | ||
109 | * The journal replaces both systemd-kmsg-syslogd and | |
110 | systemd-stdout-bridge. | |
111 | ||
112 | * New sd_pid_get_unit() API call in libsystemd-logind | |
113 | ||
114 | * Many systemadm clean-ups | |
115 | ||
116 | * Introduce remote-fs-pre.target which is ordered before all | |
117 | remote mounts and may be used to start services before all | |
118 | remote mounts. | |
119 | ||
120 | * Added Mageia support | |
121 | ||
122 | * Add bash completion for systemd-loginctl | |
123 | ||
124 | * Actively monitor PID file creation for daemons which exit in | |
125 | the parent process before having finished writing the PID | |
126 | file in the daemon process. Daemons which do this need to be | |
127 | fixed (i.e. PID file creation must have finished before the | |
128 | parent exits), but we now react a bit more gracefully to them. | |
129 | ||
130 | * Add colourful boot output, mimicking the well-known output | |
131 | of existing distributions. | |
132 | ||
133 | * New option PassCredentials= for socket units, for | |
134 | compatibility with a recent kernel ABI breakage. | |
135 | ||
136 | * /etc/rc.local is now hooked in via a generator binary, and | |
137 | thus will no longer act as synchronization point during | |
138 | boot. | |
139 | ||
140 | * systemctl list-unit-files now supports --root=. | |
141 | ||
142 | * systemd-tmpfiles now understands two new commands: z, Z for | |
143 | relabelling files according to the SELinux database. This is | |
144 | useful to apply SELinux labels to specific files in /sys, | |
145 | among other things. | |
146 | ||
147 | * Output of SysV services is now forwarded to both the console | |
148 | and the journal by default, not only just the console. | |
149 | ||
150 | * New man pages for all APIs from libsystemd-login. | |
151 | ||
152 | * The build tree got reorganized and a the build system is a | |
153 | lot more modular allowing embedded setups to specifically | |
154 | select the components of systemd they are interested in. | |
155 | ||
156 | * Support for Linux systems lacking the kernel VT subsystem is | |
157 | restored. | |
158 | ||
159 | * configure's --with-rootdir= got renamed to | |
160 | --with-rootprefix= to follow the naming used by udev and | |
161 | kmod | |
162 | ||
163 | * Unless specified otherwise we'll now install to /usr instead | |
164 | of /usr/local by default. | |
165 | ||
166 | * Processes with '@' in argv[0][0] are now excluded from the | |
167 | final shut-down killing spree, following the logic explained | |
168 | in: | |
169 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
170 | ||
171 | * All processes remaining in a service cgroup when we enter | |
172 | the START or START_PRE states are now killed with | |
173 | SIGKILL. That means it is no longer possible to spawn | |
174 | background processes from ExecStart= lines (which was never | |
175 | supported anyway, and bad style). | |
176 | ||
177 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
178 | reloading of units together. | |
