W: See /home/gitianuser/gitian-builder/base-bionic-amd64-bootstrap/debootstrap/debootstrap.log for details (possibly the package rsyslog is at fault)

duplicates #191

191 is talking about vmbuilder. I thought LXC doesn't use vmbuilder

Tested on Debian 9.5 with different repos:

gitianuser@debian:~$ apt list -a debootstrap

Listing... Done
debootstrap/unstable,now 1.0.109 all [installed]
debootstrap/testing 1.0.108 all
debootstrap/stretch-backports 1.0.100~bpo9+1 all
debootstrap/stable 1.0.89 all

• 1.0.89 from stretch doesn't work a priori;

• 1.0.100~bpo9+1 from stretch-backports doesn't work with an error while configuring rsyslog package;

• 1.0.108 from buster works as expected;

• 1.0.109 from sid works as expected.
