File name component is not a directory "/var/run/dbus"

[Felix Lechner via "Development of GNU Guix and the GNU System distribution." <guix-devel@gnu.org>]

Hi,

Guix compiled from Git (and with very minor modification) cannot
activate a system because /var/run/dbus is not a directory.  The error
message is below.

On mine, the folder is a symbolic link to /run/dbus.  Any ideas?

Did something change recently there?

Kind regards
Felix
