Currently, systemd is mostly at feature parity with Arch's initscripts. However, a lot more testing is needed. If you would like to help out, you can fork the initscripts-systemd or systemd-arch-units git repos and submit pull requests for your additions. This wiki page can serve as a staging area for these files.

If you have any questions, ask in the thread in the Arch forums.

mysqld

Note: Mysqld requires an extra script to work properly. Remember to chmod +x /usr/bin/mysqld-post before attempting to start mysqld.service
/etc/systemd/system/mysqld.service
[Unit]
Description=MySQL Server

[Service]
User=mysql
ExecStart=/usr/bin/mysqld
ExecStartPost=/usr/bin/mysqld-post
Restart=always
Timeout=30

[Install]
WantedBy=multi-user.target

#!/bin/sh
while true; do
	response=`/usr/bin/mysqladmin -uUNKNOWN_USER ping 2>&1` && break
	echo "$response" | grep -q "mysqld is alive" && break
	sleep 1
done

/etc/tmpfiles.d/mysqld.conf

mythbackend

/etc/systemd/system/mythbackend.service
[Unit]
Description=MythTV backend service
After=network.target mysqld.service

# Uncomment if using either webserver for mythweb
# Wants=httpd.service
# Wants=lighttpd.service

[Service]
Type=simple
Environment=MYTHCONFDIR=/etc/conf.d/mythbackend
Environment=HOME=/usr/share/mythtv

lircd

/etc/systemd/system/lircd.service

[Unit]
Description=LIRC Daemon
After=network.target

[Service]
Type=forking
EnvironmentFile=/etc/conf.d/lircd.conf
PIDFile=/run/lirc/lircd.pid
ExecStartPre=/bin/mkdir -p /run/lirc
ExecStartPre=/bin/rm -f /dev/lircd
ExecStartPre=/bin/rm -f /run/lirc/lircd

ExecStart=/usr/sbin/lircd -d $LIRC_DEVICE -P /run/lirc/lircd.pid -H $LIRC_DRIVER $LIRC_CONFIGFILE
ExecStopPost=/bin/rm -f /dev/lircd
ExecStopPost=/bin/rm -fR /run/lirc

[Install]
WantedBy=multi-user.target
Note: $LIRC_EXTRAOPTS does not work, so if you have anything configured in $LIRC_EXTRAOPTS in /etc/conf.d/lircd.conf, it won't be used. I tried to use Network connection via $LIRC_EXTRAOPTS (-c <ip>), lircd then always complains about the argument count. Hardcoding in the unit file works as solution.
