Actually I'm running as root , but to be more precise I'm running this
from gentoo emerge/ebuild process which setups proper
sandbox to avoid system damage.

 I've had several additional problem i managed to solve, the last one
might need proper solution in deootstrap code - details below:

# fakeroot -i debian/.fakeroot-state.debirf-libguestfs -s
debian/.fakeroot-state.debirf-libguestfs fakechroot
/usr/sbin/debootstrap --variant=fakechroot
--keyring=/usr/share/keyrings/debian-archive-keyring.gpg --include=less
--exclude=apt-utils,bsdmainutils,cron,ed,info,logrotate,man-db,manpages,tasksel,tasksel-data,tcpd,traceroute

/var/cache/apt/archives/base-passwd_3.5.20_amd64.deb

 I managed to solve it by patching debootstrap - more details below:

So something must be wrong in the debootstrap code, and the following
patch fixes it

# diff -Nru /usr/share/debootstrap/scripts/lenny.orig

Meaning in_target function defined in /usr/share/debootstrap/functions
does not work correctly.
