REQUIREMENTS:
Linux kernel >= 3.0
+ Linux kernel >= 3.3 for loop device partition support features with nspawn
+ Linux kernel >= 3.8 for Smack support
+
+ Kernel Config Options:
CONFIG_DEVTMPFS
CONFIG_CGROUPS (it's OK to disable all controllers)
CONFIG_INOTIFY_USER
CONFIG_NET
CONFIG_SYSFS
CONFIG_PROC_FS
-
- Linux kernel >= 3.8 for Smack support
+ CONFIG_FHANDLE (libudev, mount and bind mount handling)
Udev will fail to work with the legacy layout:
CONFIG_SYSFS_DEPRECATED=n
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
+ Required for PrivateNetwork in service units:
+ CONFIG_NET_NS
+
Optional but strongly recommended:
CONFIG_IPV6
CONFIG_AUTOFS4_FS
CONFIG_SCHED_DEBUG
For UEFI systems:
- CONFIG_EFI_VARS
+ CONFIG_EFIVAR_FS
CONFIG_EFI_PARTITION
Note that kernel auditing is broken when used with systemd's
runtime using the kernel command line option "audit=0", or
turn it off at kernel compile time using:
CONFIG_AUDIT=n
+ If systemd is compiled with libseccomp support on
+ architectures which do not use socketcall() and where seccomp
+ is supported (this effectively means x86-64 and ARM, but
+ excludes 32bit x86!), then nspawn will now install a
+ work-around seccomp filter that makes containers boot even
+ with audit being enabled. This works correctly only on kernels
+ 3.14 and newer though. TL;DR: turn audit off, still.
glibc >= 2.14
libcap
+ libseccomp >= 1.0.0 (optional)
libblkid >= 2.20 (from util-linux) (optional)
libkmod >= 15 (optional)
PAM >= 1.1.2 (optional)
libattr (optional)
libselinux (optional)
liblzma (optional)
- tcpwrappers (optional)
libgcrypt (optional)
libqrencode (optional)
libmicrohttpd (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.
