I totally agree to you Sam, if this is what base is supposed to be, a
very very basic group, then I don't want to see wpa_supplicant in there,
but then netctl, dhcpcd and such things should also be kicked out.

Is it possible to create a new 'network' group, with netctl
wpa_supplicant dhcpcd?

~# `pacstrap -i /mnt base base-devel network`

and pleeeaaassseeee stop talking about editors.

thanks.

cheers
