3ede835a0486f2ecc025dede0b33e9a1edc06d30Lennart Poettering When you build from git you need the following additional dependencies:

3ede835a0486f2ecc025dede0b33e9a1edc06d30Lennart Poettering During runtime you need the following dependencies:
c1c8ca815bb1ef040c0a84cccd51282e4ce8f4deKay Sievers util-linux > v2.18 (requires fsck -l, agetty -s)
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering sulogin (from sysvinit-tools, optional but recommended)

fff2e5b58bab7a5ffbb7593742d462197b06728cLennart Poettering When systemd-hostnamed is used it is strongly recommended to
fff2e5b58bab7a5ffbb7593742d462197b06728cLennart Poettering install nss-myhostname to ensure that in a world of
fff2e5b58bab7a5ffbb7593742d462197b06728cLennart Poettering dynamically changing hostnames the hostname stays resolveable
fff2e5b58bab7a5ffbb7593742d462197b06728cLennart Poettering under all circumstances. In fact, systemd-hostnamed will warn
fff2e5b58bab7a5ffbb7593742d462197b06728cLennart Poettering if nss-myhostname is not installed. Packagers are encouraged to
fff2e5b58bab7a5ffbb7593742d462197b06728cLennart Poettering add a dependency on nss-myhostname to the package that
fff2e5b58bab7a5ffbb7593742d462197b06728cLennart Poettering includes systemd-hostnamed.
6705c2df468a6afb4f8f834822780add123065e2Lennart Poettering Note that D-Bus can link against libsystemd-login.so, which
49f43d5f91a99b23f745726aa351d8f159774357Ville Skyttä results in a cyclic build dependency. To accommodate for this
6705c2df468a6afb4f8f834822780add123065e2Lennart Poettering please build D-Bus without systemd first, then build systemd,
6705c2df468a6afb4f8f834822780add123065e2Lennart Poettering then rebuild D-Bus with systemd support.
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering systemd will warn you during boot if /etc/mtab is not a
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering symlink to /proc/mounts. Please ensure that /etc/mtab is a
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering proper symlink.
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering systemd will warn you during boot if /usr is on a different
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering file system than /. While in systemd itself very little will
ed1c99fcc13f279eccf25fc20427eb92867da245Lennart Poettering break if /usr is on a separate partition many of its
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering dependencies very likely will break sooner or later in one
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering form or another. For example udev rules tend to refer to
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering binaries in /usr, binaries that link to libraries in /usr or
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering binaries that refer to data files in /usr. Since these
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering breakages are not always directly visible systemd will warn
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering about this, since this kind of file system setup is not really
21bc923aa35d455cdef1607eb7022608c705c9f3Lennart Poettering supported anymore by the basic set of Linux OS components.
