Bug#414202: apt: Unable to specify options on the command line that work via a conf file - lock errors

Package: apt
Version: 0.6.46.4-0.1
Severity: normal

This apt-conf file does work:
(In this example, /var/emdebian/sqlite is a non-privileged directory)

Dir "/var/emdebian/sqlite/"
{
  Etc "/var/emdebian/sqlite/"
  {
    SourceList "sources-debian.unstable";
  };
  State "unstable-amd64/"
  {
    Status "/var/emdebian/sqlite/status-debian"
  }
  Cache "unstable-amd64/";
};

The same options on the command line do not:

apt-get -o Apt::Dir="/var/emdebian/sqlite/" \
        -o Apt::Dir::Etc="/var/emdebian/sqlite/" \
        -o Apt::Dir::Etc::SourceList="sources-debian.unstable" \
        -o Apt::Dir::State=unstable-amd64/ \
        -o Apt::Dir::State::Status="/var/emdebian/sqlite/status" \
        -o Apt::Dir::Cache=unstable-amd64/ \
        update

Example in an arbitrary directory:
mkdir -p archives/partial 
mkdir -p lists/partial
mkdir unstable
touch status.unstable
apt-get -o Apt::Dir="$PWD" -o Apt::Dir::Etc::SourceList="sources.unstable" -o Apt::Dir::State="unstable/" -o Apt::Dir::State::Lists="lists/" -o Apt::Dir::State::Status="status.unstable" -o Apt::Dir::Cache="unstable/" update 
E: Could not open lock file /var/lib/apt/lists/lock - open (13 Permission denied)
E: Unable to lock the list directory

Despite the directories being specifically set to non-privileged
folders, apt still tries to use /var/lib/apt/

This is complicating my embedded work where it is common to require
multiple apt caches for different architectures and suites. The bug
leads to many many apt-conf.foo files being either auto-generated or
packaged alongside the script and then maintained or copied each time a
different architecture needs to be queried.

With 11 supported cross-building architectures, two suites (rising to
three, possibly four) and three buildd platforms, the permutations of
apt.conf-foo files is becoming a real problem.

When using sudo, apt-get ignores the command line options are updates
the cache files according to my /etc/apt/sources.list NOT the local
sources.unstable file that I specified on the command line.

The same errors occur with apt-cache:

$ apt-cache -o Apt::Dir="$PWD" -o Apt::Dir::Etc::SourceList="sources.unstable" -o Apt::Dir::State="unstable/" -o Apt::Dir::State::Lists="lists/" -o Apt::Dir::State::Status="status.unstable" -o Apt::Dir::Cache="unstable/" pkgnames

prints the list of pkgnames from the system cache, not the local one.

Enclosing all options within one quote does not affect the problem:

$ apt-get -o 'Apt::Dir="/var/emdebian/sqlite/"
Apt::Dir::Etc="/var/emdebian/sqlite/"
Apt::Dir::Etc::SourceList="sources-debian.unstable"
Apt::Dir::State="unstable-amd64/"
Apt::Dir::State::Status="/var/emdebian/sqlite/status-debian"
Apt::Dir::Cache="unstable-amd64/"' update
E: Could not open lock file /var/lib/apt/lists/lock - open (13 Permission denied)
E: Unable to lock the list directory

$ cd ~
$ apt-get -o Apt::Dir::State::Lists="$PWD/lists/" update
E: Could not open lock file /var/lib/apt/lists/lock - open (13 Permission denied)
E: Unable to lock the list directory

apt-(get|cache) just seem to ignore -o command line options that work fine
when using the -c <filename> method.
