This is really an OpenWrt question, but I wanted to understand the specifics
with MM. We're undergoing a security review, and it's been pointed out that
d-bus runs as non-root. I've created a new "dbus" user and group like ubus
has and have d-bus run under it as per its config file.
Everything seems OK with MM, and indeed I think this is the only user of
it under my OpenWrt setup, hence the question here.
Is this likely to break anything?
ModemManager interacts with hardware drivers themselves, it needs some rather
elevated capabilities. A non-root user won't work immediately; you'd need to
make sure that the user can access all the lower layer in the hardware stack.
The question isn't about ModemManager running as another user, it's about
d-bus, of which MM is the only user on OpenWrt on my system. As far as I can
tell, it works fine.
