what's wrong with output? can you post the output verbatim? I had a
look at the init script and it doesn't seem to print much.

not quite sure what "/dev/null >&" would do. I tried this with
net.eth0:
sudo /etc/init.d/net.eth0 restart >/dev/null

and it got rid of all the output. To be sure, you could add 2>&1
sudo /etc/init.d/net.eth0 restart >/dev/null 2>&1

yes, I know I was just using net.eth0 as an example because I was
too lazy to install networkmanager and see for myself!

Did you try my suggestion?

> > sudo /etc/init.d/net.eth0 restart >/dev/null 2>&1

did it help? (substitute net.eth0 with NetworkManager

It looks like all the output comes from this line in the init script
(again, only looking in the source, so YMMV)
start-stop-daemon --start --quiet --exec ${processname}

try adding
>/dev/null 2>&1
to the end of it.

aaaaaaaaahhhhhhhhhhhh i see...

I thought you were on console 1, I didn't realise that NetworkManager
printed output to console 1 even if you started it from elsewhere... Now
I get it!

yes, won't work given what you've said...

Sounds like NetworkManager is using syslog() to write to the log file,
and you have syslog set up to notify you. This usually happens by
printing messages to console 1! NetworkManager seems to translate glib
errors directly to syslog errors. Have a look at nm-logging.c if you
want to see more about that.

Anyway, depending on the logger you use (I use syslog-ng) you can set it
up not to be so verbose. syslog-ng allows you to filter based on
program name for example. man syslog-ng.conf for more info (or whatever
logger you use

Have a look at http://www.campin.net/syslog-ng.conf for some examples.
