CONFIG_EPOLL
CONFIG_NET
CONFIG_SYSFS
+ CONFIG_PROC_FS
+ CONFIG_FHANDLE (libudev, mount and bind mount handling)
Linux kernel >= 3.8 for Smack support
Some udev rules and virtualization detection relies on it:
CONFIG_DMIID
- Mount and bind mount handling might require it:
- CONFIG_FHANDLE
-
Support for some SCSI devices serial number retrieval, to
create additional symlinks in /dev/disk/ and /dev/tape:
CONFIG_BLK_DEV_BSG
CONFIG_TMPFS_XATTR
CONFIG_SECCOMP
- For systemd-bootchart, a kernel with procfs support and
- several proc output options enabled is required:
- CONFIG_PROC_FS
+ For systemd-bootchart, several proc debug interfaces are required:
CONFIG_SCHEDSTATS
CONFIG_SCHED_DEBUG
glibc >= 2.14
libcap
+ libseccomp >= 1.0.0 (optional)
libblkid >= 2.20 (from util-linux) (optional)
libkmod >= 15 (optional)
PAM >= 1.1.2 (optional)
libpython (optional)
make, gcc, and similar tools
+ To sucessfully use --compat-libs, gcc >= 4.8 seems necessary.
+
During runtime, you need the following additional
dependencies:
- util-linux >= v2.19 (requires fsck -l, agetty -s)
+ util-linux >= v2.19 (requires fsck -l, agetty -s),
+ v2.21 required for tests in test/
dbus >= 1.4.0 (strictly speaking optional, but recommended)
- sulogin (from util-linux >= 2.22 or sysvinit-tools, optional but recommended)
+ sulogin (from util-linux >= 2.22 or sysvinit-tools, optional but recommended,
+ required for tests in test/)
dracut (optional)
PolicyKit (optional)
gperf
gtkdocize (optional)
python (optional)
+ python-lxml (optional, but required to build the indices)
sphinx (optional)
- python-lxml (entirely optional)
When systemd-hostnamed is used, it is strongly recommended to
install nss-myhostname to ensure that, in a world of
about this, since this kind of file system setup is not really
supported anymore by the basic set of Linux OS components.
+ systemd requires that the /run mount point exists. systemd also
+ requires that /var/run is a a symlink → /run.
