Package: pbuilder
Version: 0.230.4
Severity: important
Tags: upstream

Hi,

I tried to upgrade my Docker-based pbuilder containers from stretch to
buster. However it appears that pbuilder and/or debootstrap do not work
properly inside Docker containers any longer due to issues with mounting
special filesystems such as proc and devpts.

The issue can be reproduced easily in a Debian Buster based container:

# docker run --privileged -it debian:buster /bin/bash

debootstrap.log contains the following message regarding the proc mount

mount: /proc: mount(2) system call failed: Too many levels of symbolic links.

Thank you for looking into this issue. Until then I'll continue to use
the stretch-based pbuilder container and use it to build packages for buster.

Best regards

Tobias
