Package: ifupdown Version: 0.6.8 Severity: normal Tags: patch While dhclient is started with the -e option to fail and exit when no leases could be acquired, dhclient3 is not. As a result, the interface comes up unconfigured in that case.
The changelog states that the -1 option of dhclient3 is not used,
because dhclient3 would not daemonize at all:
--8<---
+ Avoids inconsistency in interface state if the command run
by ifup fails, also added -e option to dhclient in order to
have it return an error if it cannot get an address.
Notice that this is not yet done with dhclient3 (-1) since that would
mean not running dhclient3 as a daemon and renews not being done.
(Closes: #97782, #82339, #113338, #148666, #169194)
--8<---
However, both looking at the source and trying it using the attached
patch shows that -1 in dhclient3 is implemented nearly identical to -e
in dhclient and that dhclient3 with the -1 option does daemonize and
renew its lease fine when it did acquire one in the first place (and
fail otherwise).
