Subject: [bug#36141] [PATCH] installer: Unblock relevant rfkill switches.
Date: Sat,  8 Jun 2019 19:55:05 +0200

* gnu/installer/connman.scm (connman-enable-technology): Call ‘rfkill’
to (soft-)unblock a wireless technology before enabling it.

Guix,

Scanning for Wi-Fi networks on a Dell Latitude E6400 shows nothing
before running ‘rfkill unblock all’ on another VT.

Do this automatically, and more specifically.

K-regs,

T G-R
