Meet netctl: a profile based networking CLI using systemd. In the near future,
the old netcfg will be removed from [core]. Anyone using it is urged to move to
netctl. Migration is a manual process during which you might not have access to
the Internet, so take care and read the man pages (netctl(1), netctl.profile(5)
The design of netctl is so that systemd enthusiasts will appreciate its usage
and netcfg users will be familiar with its profile files. Shipped with netctl
comes a ncurses-based wifi connection assistant called wifi-menu.
As you install netctl, netcfg will be removed, but the enabled systemd services
will remain until manually disabled. The [netctl wiki] holds some additional
information on migrating from netcfg.
