Title:
Trailing dot in fqdn of ps5 VMs regresses some tests (e.g. postfix)
Status in Auto Package Testing:
In Progress
Bug description:
On ps5 amd64 VMs (lcy02) we have that:
$ hostname --fqdn
adt-paride-mantic-postfix.openstack.prodstack5.lan.
Note the trailing dot. This causes regressions in some packages, see
for example LP: #2019195. Ideally we should fix the regressed packages
(the trailing dot is technically correct), but it makes sense to
workaround the problem while the packages are getting fixed. Some
possibilities are:
(1) Remove `manage_etc_hosts: true` from the cloud-init user-data used
by the create-nova-image-new-release script. This should prevent the
hostname to be set to the name advertised by openstack, and left to
the static string 'autopkgtest'. I did some git archeology and
manage_etc_hosts initially came from this snippet:
# unbreak my server option :-(
userdata=`mktemp`
trap "rm $userdata" EXIT TERM INT QUIT PIPE
/bin/echo -e "#cloud-config\nmanage_etc_hosts: True" > $userdata
and that was the *only* use of user-data back then. Looks like it was
a workaround for some issue? In any case I can't be sure that
disabling manage_etc_hosts won't cause other issues.
(2) Remove the trailing dot in /etc/hosts using the setup-canonical.sh
script, e.g.
sed -Ei '/^127\.0\.1\.1 /s/([a-z])\. /\1 /' /etc/hosts
I don't think this can be racey with cloud-init reconfiguring the
hostname because testbed-setup removes cloud-init. Cons of this
approach: very hacky. We ask cloud-init to manage /etc/hosts (via
manage_etc_hosts), but then mangle it manually (not nice).
