NetworkManager brings up devices asynchronously, ie. it doesn't block
during boot until a interface is up. So your problem wouldn't really be
fixed, as your boot process would still be racy. Does I don't think the
/etc/init.d/network-manager init script should provide $network.

It does provide ifupdown integration to some extent, i.e. it runs the
if-up.d/if-down.d hooks when interfaces are taken out / brough down.
Doesn't samba also use ifupdown hooks to get notification about network
changes? How does samba deal with the fact that a network is possibly
not up during boot?

Imho, a the correct way to fix this, is to fix samba to make it listen
for network changes (via netlink).

There is another hack (which of course I don't recommend to be added to
the samba Debian package):

Change /etc/init.d/samba and add a call to "nm-online" before you start
the samba daemons.
This tool will exit as soon as NetworkManager has established a network
connection. It will exit after a 30 second timeout, if no connection
could be established during that time. So your boot won't block
indefinitely.

To sum up: I don't plan to add  Provides: $network to the NM init
script, for the given reasons.
Also, $network is a virtual facility, which I can't simply modify by
adding a "Provides: $network" to the LSB header, as insserv doesn't
allow that.

So, I'm not sure what to do about this bug in network-manager. If it
should be re-assigned/closed/...

Cheers,
Michael
