[Bug 1271455] [NEW] lxc-create does not honor $HTTP_PROXY when using a cached base image

[Martin Pitt]

Public bug reported:

I just learned that one can call lxc-create with $HTTP_PROXY set to
configure an apt proxy in the container. However, this only seems to
work when it actually downloads and creates a base image. When it's
using a cache it doesn't work:

$ sudo HTTP_PROXY=http://donald:3142 lxc-create -t ubuntu -n precise-i386 -- -r precise -a i386
Checking cache download in /var/cache/lxc/precise/rootfs-i386 ... 
Copy /var/cache/lxc/precise/rootfs-i386 to /scratch/lxc/precise-i386/rootfs ... 
Copying rootfs to /scratch/lxc/precise-i386/rootfs ...
[...]

$ ls -l /scratch/lxc/precise-i386/rootfs/etc/apt/apt.conf.d/
insgesamt 16
-rw-r--r-- 1 root root 350 Nov 15 16:35 01autoremove
-rw-r--r-- 1 root root 372 Jan 22 10:08 01autoremove-kernels
-rw-r--r-- 1 root root 123 Apr 20  2012 20changelog
-rw-r--r-- 1 root root 182 Mär 15  2012 70debconf

i. e. there is no 70proxy.

When appending -F it works. However, 70proxy is *not* in the cache, so
lxc-create does create that after creating the cache. Hence it should
not be too difficult to also create 70proxy after copying an existing
cache?
