1. import backports.org archive key to my normal apt-keys
2. copy /etc/apt/ to /foo/
3. remove everything but trustdb.* to make /foo/trustdb.* only.
4. "pbuilder --create -p foo -d lenny-backports --aptconf /foo"

--aptconf will copy trustdb.* to chroot and accessing backports will not error.

case "foo" in
foo|bar)
        echo foo-or-bar
        ;;
esac

This output "foo-or-bar"

FOOBAR="foo|bar"
case foo in
$FOOBAR)
        echo foo-or-bar
        ;;
esac
 
This output nothing.

FOOBAR="foo|bar"
case "foo|bar" in
$FOOBAR)
        echo foo-or-bar
        ;;
esac

This output "foo-or-bar"

Using "eval" is needed to enable splitting choices with |.

My rationale were:

one wants to compile package for some proposed-archive or
security-archive while using all the updated backage as its parents and
supplimented with base distribution via APT while it needs to be created
by debootstrap using its base distribution.

It is easier to explain with a table.

 --distribution option   debootstrap          APT line
 target distribution(T)  base distribution(B) T+B
 $DISTRIBUTION           $DISTRIBUTION_BASE

 jaunty-updates          jaunty               jaunty-updates jaunty
 lenny-proposed-...      lenny                lenny-proposed-...  lenny
 lenny                   lenny                lenny


If you have clearler naming convention, let me know.
