499519c6499e92d1953fd79b99a805b9278d5ea1Lennart Poettering When you build from git you need the following additional dependencies:
5965984d6b9f7751d6281028142ecf3ca475f156Lennart Poettering make, gcc, and similar tools
e41814846c19a48f4490169d82e359e005c4db45Lennart Poettering During runtime you need the following dependencies:
e9fd44b728ff1fc0d1f24fccb87a767f6865df27Lennart Poettering util-linux > v2.18 (requires fsck -l, agetty -s)
15abdb9a6f34628b04b887e0b9649fa582d6cd37Lennart Poettering sulogin (from sysvinit-tools, optional but recommended)
e9fd44b728ff1fc0d1f24fccb87a767f6865df27Lennart Poettering plymouth (optional)

15abdb9a6f34628b04b887e0b9649fa582d6cd37Lennart Poettering When systemd-hostnamed is used it is strongly recommended to
8ed206517c2be381324ac5832bf34cc14024270eLennart Poettering install nss-myhostname to ensure that in a world of
e6c6e7afffa80ad74efdb1ddfa815294624f1608Lennart Poettering dynamically changing hostnames the hostname stays resolveable
e6c6e7afffa80ad74efdb1ddfa815294624f1608Lennart Poettering under all circumstances. In fact, systemd-hostnamed will warn
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering if nss-myhostname is not installed. Packagers are encouraged to
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering add a dependency on nss-myhostname to the package that
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering includes systemd-hostnamed.
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering Note that D-Bus can link against libsystemd-login.so, which
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering results in a cyclic build dependency. To accomodate for this
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering please build D-Bus without systemd first, then build systemd,
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering then rebuild D-Bus with systemd support.
7361c3b4e1e28a7eb4354a3da354b22e79782141Lennart Poettering systemd will warn you during boot if /etc/mtab is not a
7361c3b4e1e28a7eb4354a3da354b22e79782141Lennart Poettering symlink to /proc/mounts. Please ensure that /etc/mtab is a
e673ad0415d89c322e5b1a121e411f1b1d8075c0Lennart Poettering proper symlink.
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers systemd will warn you during boot if /usr is on a different
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers file system than /. While in systemd itself very little will
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers break if /usr is on a separate partition many of its
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers dependencies very likely will break sooner or later in one
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers form or another. For example udev rules tend to refer to
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers binaries in /usr, binaries that link to libraries in /usr or
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers binaries that refer to data files in /usr. Since these
f6113d42d015ad9f3a9e702a09eb8006511a4424Kay Sievers breakages are not always directly visible systemd will warn
f6113d42d015ad9f3a9e702a09eb8006511a4424Kay Sievers about this, since this kind of file system setup is not really
d2e83c23f5f0cdd3b6ec05c5c40209708721e704Kay Sievers supported anymore by the basic set of Linux OS components.
