Package: fakechroot
Version: 2.19-3
Severity: normal
Tags: patch
Dear Maintainer,
debootstrap may fail in a fakechroot environment if systemd is not installed or
if
the architectures inside and outside of the (fake)chroot don't match.
This doesn't occur if the patch below is applied.
The cause is systemctl version 232-15 finding a library through a DT_RUNPATH
tag
(ie outside of the (fake)chroot)).
systemctl is invoked in the maintainer scripts of systemd.
$ readelf -d mychroot-amd64/bin/systemctl
