apt ignores -o DPkg::Options ?

["Nikita V. Youshchenko" <yoush@cs.msu.su>]

Hmm...

Seems that apt-get ignores -o DPkg::Options.

nikita@zigzag:~> cat /tmp/xxx
#!/bin/sh
echo dpkg $*
exit 1

nikita@zigzag:~> LANG=C apt-get -o 'Dir::Bin::dpkg=/tmp/xxx' -o
'DPkg::Options={"--xxx";}' install nvi

E: Sub-process /tmp/xxx returned an error code (1)

So dpkg is called without any options from DPkg::Options ...

Should this be reported as a bug in apt, or I am doing something wrong?

P.S.
While exploring this issue, I looked at apt open bug list. I was surprised
how HUGE it is. Can't believe that apt, possibly the most important Debian
package, is poorly maintained...
