Public bug reported:
This happens on Utopic. Trusty is fine. Steps to reproduce:
sudo lxc-create -t ubuntu-cloud -n utopic -- -F -s daily -r utopic
sudo lxc-start-ephemeral -o trusty -n test -d
sudo lxc-attach -n test -- login -f root
Examine /etc/apt/sources.list inside the host. For example, "cat
/etc/apt/sources.list" shows the subsequent prompt at the end of the
last line instead of on a fresh line. "vim /etc/apt/sources.list" says
"noeol".
Expected: newline at end of file, following Unix convention.
Actual: no newline at end of file.
Impact: messes up my local script that does trivial manipulations (adds
a local repository).
I've examined the sources.list shipped with the image, and it doesn't
have this problem and the sources.list I see after startup looks
radically different (matching the template in /etc/cloud/...). So it
seems to me that the templating mechanism inside cloud-init is causing
this.
