zh-cn:Daemons List

Tango-view-refresh-red.pngThis article or section is out of date.Tango-view-refresh-red.png

Reason: The table lists deprecated netcfg services, they should be replaced by netctl services. However, netctl does not work with initscripts, which is why netctl should not be listed in this table. (Discuss in Talk: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/.

For each daemon the name of the script (for initscripts) and of the service (for systemd) is given.
