Hi all
When fiddling around trying to replace networkmanager with wpa_gui from
wpa_supplicant, I came across a problem in /lib/services/wpa from
blfs-bootscripts-20160415.
As wpa_gui does not use dbus/polkit for access rights, but plain unix
group write permissions on the socket, I put in my
/etc/sysconfig/wpa_supplicant-wifi0.conf the following line:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
update_config=1
When starting wpa_supplicant and dhcpcd manually, I could then use
wpa_gui as normal user with wheel group membership to manage my access
points and all was well.
But when I set it all up proper in lfs, it wouldn't work anymore. The
reason is that the blfs service file explicitely sets the ctrl_interface
on the commandline, overriding the setting in the config file. Sadly,
the man page of wpasupplicant describes no method to provide the group
information on the command line.
The following diff fixes the wpa service script, allowing wpa_gui (and
wpa_cli) to be used as a regular user.

It might also be an idea to mention this on the wpasupplicant page, that
in order to manage access points,
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel
update_config=1
can be used in the config.
