Daemons List - ArchWiki

# Daemons List

Here is a list of daemons. Note that any package can provide a daemon, so this list will never be complete. Please feel free to add any missing daemons here, in alphabetical order. You may have packages that include other daemons from the AUR. These files will likely be located in `/usr/lib/systemd/system/`.

The Package column contains a link to ArchWiki page for each daemon (or link to the package if no such page exists). The initscripts column contains the name of the script for initscripts and the systemd column contains the name of the systemd service file. Note that there may be daemons specific to either initscripts or systemd, with the respective column empty. The Description column provides short description, preferably of the daemon (not of the package).
