Subject: [PATCH 07/18] tests: Correctly handle domain search list in dhclient-script
Date: Fri, 15 Jul 2022 15:21:30 +1000 [thread overview]
Message-ID: <20220715052141.890703-8-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20220715052141.890703-1-david@gibson.dropbear.id.au>

Currently our small custom dhclient-script only handles the 'domain-name'
option, which can just list a single domain, not the 'domain-search'
option, which can handle several. Correct it to handle both.
We also weren't emptying the resolv.conf file before we began, which
could lead to surprising contents after multiple DHCP transactions.
