elogind is the systemd project's logind, extracted to a standalone package. It's designed for users who prefer a non-systemd init system, but still want to use popular software such as KDE/Wayland or GNOME that otherwise hard-depends on systemd.
The following kernel options are recommended:
General setup ---> [*] Control Group support ---> File systems ---> [*] Inotify support for userspace Security options ---> [*] Enable different security models [*] Simplified Mandatory Access Control Kernel Support
In the unlikely (and not recommended) event that standard kernel features are enabled for manual configuration, elogind also requires
timerfd() support. Most users can ignore this.
USE flags for sys-auth/elogind The systemd project's logind, extracted to a standalone package
There is a global
elogind USE flag for enabling elogind support in other packages. It's also recommended to disable support for other session trackers to avoid conflicts:
USE="elogind -consolekit -systemd"
After updating your USE flags update the system so the changes take effect:
emerge --ask --changed-use --deep @world
elogind may be optionally configured to start at boot time:
rc-update add elogind boot
Alternatively, elogind will be launched automatically when the first service calls it via dbus, or if built with
USE="pam", when the first user logs into the system.
