Hi,

I have setup a 'share connection with other computers' type of
connection in NetworkManager, via 'sudo -E nm-connection-editor', and it
works, e.g. to allow a device connected to my 2nd Ethernet port to get a
dynamic IP address and have access to the Internet, but, in
/var/log/messages, I see:

This gets repeated spuriously in /var/log/messages.  There's at least a
problem with /sbin/modprobe not being looked at the right place.
Interestingly, it also seems to trigger a crash in Jami, which does some
connection refreshing work on events from NetworkManager [0].

Fixed with:

ef71e32909 origin/master services: network-manager: Set LINUX_MODULE_DIRECTORY 
environment variable.
e682932636 gnu: network-manager: Patch modprobe file name.

Closing!
