 AUTHOR:
         Lennart Poettering with major support from Kay Sievers
 
+LICENSE:
+        GPLv2+ for all code, except sd-daemon.[ch] which is MIT
+
 REQUIREMENTS:
-        Linux kernel >= 2.6.30 (with autofs4, devtmpfs and the debug cgroup controller)
-        libudev >= 151
-        libcgroup >= 0.35
-        vala >= 0.80
-        gtk+ >= 2.20
-        dbus >= 1.2.24
+        Linux kernel >= 2.6.30 (with devtmpfs, cgroups; optional but strongly recommended: autofs4, ipv6)
+        libudev >= 172
+        dbus >= 1.4.0
+        libcap
+        gtk+ >= 2.20 (optional)
+        PAM >= 1.1.2 (optional)
+        libcryptsetup (optional)
+        libaudit (optional)
+        libselinux (optional)
+        tcpwrappers (optional)
+        libnotify (optional)
+
+        When you build from git you need the following additional dependencies:
+
+        vala >= 0.10
+        docbook-xsl
+        xsltproc
+        automake
+        autoconf
+        libtool
+        make, gcc, and similar tools
+
+        During runtime you need the following dependencies:
+
+        util-linux > v2.18 (requires fsck -l, agetty -s)
+        sulogin (from sysvinit-tools, optional but recommended)
+        plymouth (optional)
+        dracut (optional)
+
+        When systemd-hostnamed is used it is strongly recommended to
+        install nss-myhostname to ensure that in a world of
+        dynamically changing hostnames the hostname stays resolveable
+        under all circumstances. In fact, systemd-hostnamed will warn
+        if nss-myhostname is not installed. Packagers are encouraged to
+        add a dependency on nss-myhostname to the package that
+        includes systemd-hostnamed.
+
+WARNINGS:
+        systemd will warn you during boot if /etc/mtab is not a
+        symlink to /proc/mounts. Please ensure that /etc/mtab is a
+        proper symlink.
+
+        systemd will warn you during boot if /usr is on a different
+        file system than /. While in systemd itself very little will
+        break if /usr is on a separate partition many of its
+        dependencies very likely will break sooner or later in one
+        form or another. For example udev rules tend to refer to
+        binaries in /usr, binaries that link to libraries in /usr or
+        binaries that refer to data files in /usr. Since these
+        breakages are not always directly visible systemd will warn
+        about this, since this kind of file system setup is not really
+        supported anymore by the basic set of Linux OS components.
