+ Linux kernel >= 3.0
+ CONFIG_DEVTMPFS
+ CONFIG_CGROUPS (it's OK to disable all controllers)
+ CONFIG_INOTIFY_USER
+ CONFIG_SIGNALFD
+ CONFIG_TIMERFD
+ CONFIG_EPOLL
+ CONFIG_NET
+ CONFIG_SYSFS
+
+ Linux kernel >= 3.8 for Smack support
+
+ Udev will fail to work with the legacy layout:
+ CONFIG_SYSFS_DEPRECATED=n
+
+ Legacy hotplug slows down the system and confuses udev:
+ CONFIG_UEVENT_HELPER_PATH=""
+
+ Userspace firmware loading is deprecated, will go away, and
+ sometimes causes problems:
+ CONFIG_FW_LOADER_USER_HELPER=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
+
+ Optional but strongly recommended:
+ CONFIG_IPV6
+ CONFIG_AUTOFS4_FS
+ CONFIG_TMPFS_POSIX_ACL
+ CONFIG_TMPFS_XATTR
+ CONFIG_SECCOMP
+
+ For systemd-bootchart a kernel with procfs support and several
+ proc output options enabled is required:
+ CONFIG_PROC_FS
+ CONFIG_SCHEDSTATS
+ CONFIG_SCHED_DEBUG
+
+ For UEFI systems:
+ CONFIG_EFI_VARS
+ CONFIG_EFI_PARTITION
+
+ Note that kernel auditing is broken when used with systemd's
+ container code. When using systemd in conjunction with
+ containers please make sure to either turn off auditing at
+ runtime using the kernel command line option "audit=0", or
+ turn it off at kernel compile time using:
+ CONFIG_AUDIT=n
