Re: guix shell set user groups to access security token

[Alexander Asteroth <alexander.asteroth@h-brs.de>]

Thank's for the simple workaround. It helped to find out that the error
is not caused by the user's group ids. In fact it's related to missing
network access. I solved it by providing --network to the shell but
unfortunately this only worked exactly one single time. Now as soon as I
enable the network, the usb-connection to the token vis /dev/sg0 is not
estblished at all. Very strange (in particular, that it worked one
time).
