Note that because of the Bashisms whatever address was negotiated is not assigned. This applies at least to IPv6, and if the bashisms interfere in IPv4 then it also interferes there.
This means the essential function of the application does not operate, and the bug should potentially be a higher severity level. (I'm setting to High because it "renders essential features or functionality of the application or dependencies broken or ineffective" - which is defined as a "High" criterion in the Bug Importance page of the bugsquad documentation) ** Changed in: isc-dhcp (Ubuntu) Importance: Low => High -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to isc-dhcp in Ubuntu. https://bugs.launchpad.net/bugs/1448690 Title: /sbin/dhclient-script has bashisms Status in isc-dhcp package in Ubuntu: Confirmed Bug description: /sbin/dhclient-script calls /bin/sh, which is of course dash, but contains bash-specific functions: root@mystic:~# ifup br0 Internet Systems Consortium DHCP Client 4.3.1 Copyright 2004-2014 Internet Systems Consortium.
