Most up to date Systemd REQUIREMENTS:
http://cgit.freedesktop.org/systemd/systemd/tree/README#n36
REQUIREMENTS:
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
Create /etc/portage/profile/use.force with -consolekit.
$ cat /etc/portage/profile/use.force
-consolekit
Create /etc/portage/profile/use.mask with consolekit and -systemd.
$ cat /etc/portage/profile/use.mask
consolekit
-systemd
Add to package.use.
$ cat /etc/portage/package.use
sys-fs/udisks systemd
sys-auth/polkit systemd
sys-auth/pambase systemd
When you install systemd you must have desktop profile set.
# eselect profile list
Available profile symlink targets:
[1] default/linux/amd64/13.0
[2] default/linux/amd64/13.0/selinux
[3] default/linux/amd64/13.0/desktop *
[4] default/linux/amd64/13.0/desktop/gnome
[5] default/linux/amd64/13.0/desktop/kde
[6] default/linux/amd64/13.0/developer
[7] default/linux/amd64/13.0/no-multilib
[8] default/linux/amd64/13.0/x32
[9] hardened/linux/amd64
[10] hardened/linux/amd64/selinux
[11] hardened/linux/amd64/no-multilib
[12] hardened/linux/amd64/no-multilib/selinux
[13] hardened/linux/amd64/x32
[14] hardened/linux/uclibc/amd64
"OPS" It is very important you don't reboot without one or the other installed. The results would be rather unfortunate.
I use xfce4 and that means only remove udev. Consolekit get removed with above settings.
emerge -C udev
Install systemd first then add systemd to make.conf.
emerge -1av systemd
Add systemd to make.conf.
USE="-gnome -kde -minimal -qt4 -consolekit -pulseaudio systemd
Update your system.
emerge --keep-going --update --newuse --ask --deep --with-bdeps=y @world
Add systemd to grub2.
GRUB_CMDLINE_LINUX="init=/usr/lib/systemd/systemd"
Mine looks like this.
GRUB_CMDLINE_LINUX="quiet audit=0 ipv6.disable=1 init=/usr/lib/systemd/systemd"
Done with systemd and reboot.

Start Network
systemctl enable NetworkManager
systemctl start NetworkManager
If you have dhcpcd.
systemctl enable dhcpcd.service
If it doesn´t work
systemctl enable dhcpcd@interface_name.service
If you use dhclient.

If you have trouble with mounting usb ,burning with dvd.not login to tty a.s.o,
check if your user-session is active. (google have alot from arch linux forum)

I fix this with the simplest solution. I installed lightDM displaymanager.
https://wiki.archlinux.org/index.php/LightDM
systemctl enable lightdm
If you want to have another display manager.
Enable with.
for kdm
systemctl enable kdm.service
systemctl start kdm.service
for gdm
systemctl enable gdm.service
systemctl start gdm.service

If you have a large /home partition, it might be better to allow services that do not depend on /home to start while /home is checked by fsck. This can be achieved by adding the following options to the /etc/fstab entry of your /home partition.
noauto,x-systemd.automount

Early start for services
One central feature of systemd is D-Bus and socket activation. This causes services to be started when they are first accessed and is generally a good thing. However, if you know that a service (like UPower) will always be started during boot, then the overall boot time might be reduced by starting it as early as possible. This can be achieved (if the service file is set up for it, which in most cases it is) by issuing.
# systemctl enable upower
----------------------------------------------------------------------------------------------------
After install i would recommend if you still have openrc installed but wants systemd to take care of how programs starts. And maby save some time on boot.
To check in terminal - rc-update show.
I removed to start with.
dbus
networkmanager
alsa
syslog-ng (uninstalled)
----------------------------------------------------------------------------------------------------
Systemd comes with a rumour to boot fast and that is all true.
Look at this thread at arch linux forums. This thread is very good and you got many tips and trix from other users.
Post your systemd startup times
https://bbs.archlinux.org/viewtopic.php?id=147841
Command in terminal : systemd-analyze && systemd-analyze blame
or like me in .bashrc
alias sys='systemd-analyze && systemd-analyze blame'
And here you have my boot times at the moment.
Startup finished in 4.997s (firmware) + 961ms (loader) + 1.128s (kernel) + 535ms (userspace) = 7.622s
Whats interest are those numbers :) and yes i have an intel 180g ssd.
Startup finished in 1.128s (kernel) + 535ms (userspace) =1.633

And if you have an more advanced setup with encryption,initramfs.You should look at user nlsa8z6zoz7lyih3ap´s thread on gentoo forums.
