Description Michal Maruška 2013-10-02 08:50:25 UTC 
dhclient.conf(5)  documents "script" option.

NM invokes dhclient with  -sf option, providing its helper tool to be invoked.

Apparently  dhclient can use only one of those two, so, if an unaware user enables the "script" option ... to run dhclient-script(8) and promised hooks, suddenly the NM handled connection(s) are lost after a while.

I use 0.9.4.0-0ubuntu4.3
Comment 2 Pavel Simerda 2013-10-02 09:20:05 UTC 
Ah, just found the fix in git master:

commit 97990135f150237eb7d529894fb0149d9faa5f0f
Author: Dan Williams <dcbw@redhat.com>
Date:   Wed Feb 27 14:49:25 2013 +0100

    dhcp: ensure any dhclient script from dhclient.conf is ignored
    
    The config file can specify a dhclient script, which gets used instead
    of what NM passes on the command-line.  Make sure that script gets
    ignored in the final dhclient config, because the script NM passes
    is the script that needs to be used to pass data back to NM.  People
    may have old dhclient.conf files lying around that get picked up and
    we don't want any script specified there to interfere.

But it didn't get to any 0.9.8 update. Adding Dan Williams to Cc to decide about inclusion in the stable branch.
