git ubuntu build-source fails on cosmic for postfix

[Karl Stenerud]

[Impact]

Attempting to use git-ubuntu to build postfix under cosmic fails, complaining about not having permissions open a tarball.

[Test Case]

$ git-ubuntu clone postfix
$ cd postfix
$ lxc image list
...
| | 5a0e42b9ea44 | no | ubuntu 18.10 amd64 (daily) (20180829) | x86_64 | 175.40MB | Aug 30, 2018 at 6:14pm (UTC) |
...
Get an 18.10 image ID. In this case: 5a0e42b9ea44

$ git ubuntu build-source -v --lxd-image 5a0e42b9ea44 --sign --keep-build-env

It will fail with:

09/07/2018 18:00:00 - ERROR:Command exited 2: /usr/bin/lxc exec moved-mutt -- sudo -s -H -u ubuntu tar zxCf /tmp /tmp/tmptsr1sluv.tar.gz
09/07/2018 18:00:00 - ERROR:stdout:
09/07/2018 18:00:00 - ERROR:stderr: tar (child): /tmp/tmptsr1sluv.tar.gz: Cannot open: Permission denied

If you look inside the container, you'll see:

# ls -l /tmp/tmptsr1sluv.tar.gz
-rw------- 1 1001 1001 4673602 Sep 7 18:00 /tmp/tmptsr1sluv.tar.gz

Pretty sure this is a duplicate of bug 1749609.

You are right, Scott. I think we need to do a uid map to avoid this?
