Linux – Arch Linux – Cannot start CUPS service with systemd

• Remove lpr (and lprng). The stand-alone version of lpr will complain if confronted with options that are passed along via -o.

• Install cups-bsd. This brings along a version of lpr that accepts things like -o and other common parameters used by acroread. (cups-bsd conflicts with lpr or lprng).

• Look closely and read that acroread recommends cups-bsd.

mysqld.service is a "virtual" unit – it doesn't exist on the filesystem, it's just part of systemd's compatibility layer. You can start it and systemd will run the legacy /etc/rc.d/mysqld initscript, but you cannot systemctl enable it because you need a real .service file which could be symlinked into the proper place.

You can write such a unit yourself and put it in /etc/systemd/system/mysqld.service:

[Unit]
Description=MySQL Server
After=network.target

[Service]
ExecStart=/usr/bin/mysqld --defaults-file=/etc/mysql/my.cnf --datadir=/var/lib/mysql --socket=/var/run/mysqld/mysqld.sock
User=mysql
Group=mysql
WorkingDirectory=/usr

[Install]
WantedBy=multi-user.target

Run systemctl daemon-reload after creating/modifying.

Alternatively, you can install the initscripts-systemd package, which includes arch-daemons.target for automatically starting services defined in rc.conf. However, this package might go away soon, and it's always better to have native configuration files for the init system in use.
