[Buildd-tools-devel] Bug#376020: sbuild: APT_OPTIONS and DEBIAN_FRONTEND are dropped inside the chroot when running dpkg

[Roger Leigh]

Package: sbuild
Version: 0.47
Severity: important

When running a command in the chroot, sudo is run a second time inside
the chroot:

/usr/bin/sudo /usr/sbin/chroot /home/rleigh/build/chroot-unstable
/usr/bin/sudo -H /bin/sh -c '/usr/bin/dpkg --purge libncurses5-dev m4
dictionaries-common-dev dictionaries-common wamerican texi2html wbritish
bison texinfo 2>&1 </dev/null'

This means that

root    ALL=(ALL) ALL
Defaults:root env_keep+="APT_CONFIG DEBIAN_FRONTEND"

needs adding to /etc/sudoers inside the chroot to prevent the
environment being stripped.


Ideally, we should be able to replace the use of sudo with su (inside
the chroot) when using sudo on the host system.  See Sbuild/Chroot.pm,
lines 250-256.


Regards,
Roger
