Thanks, I didn't notice it was since 2.6.12. woody dpkg was long broken. I've only seen more recent reports about this. To fix this problem, will require update to dpkg in woody; which might not be feasible. We could drop support of woody chroots in etch. It might be possible to add a workaround hack in [c]debootstrap to trap mmap; or fill status/available files before invoking dpkg. I'm not quite sure why sarge manages to bootstrap despite having a dpkg version (1.10.28) that shouldn't work. regards, junichi
