The service and initscript have "connmand" name
while the package is called "connman" indeed.

Shame on me; this became apparent
while building regular-e18-sysv.

A bit longer version is: add the script which cares to protect
the interfaces which has been brought up during NFS root bootup
already from being tampered with by NetworkManager so as to avoid
losing network with networked rootfs.

This is to avoid NM messing with network interface
involved in NFS root filesystem being operational
(see alterator-netinst); thanks sem@ for the hint.

Intro: NetworkManager-wait-online.service would, well, wait
for some network interface to become online or for timeout
to kick in.

Problem: if a LiveCD is tested in offline environment
that timeout will only impede the boot.

Proposed solution: use/net/nm/nodelay target has been implemented
to disable that service as proposed by sem@ and done in Simply;
"+nm" target changed to be an alias to this one.

...net uses services, not services use net.  That is,
"network" is a service that needs to be enabled by the
now-existing mechanism of "services" feature, don't be
fooled by "network services" here.

This one supports /etc/net, NM and connman; pruning the tree
to get rid of hardwired remnants is going to take some more time.
