I suppose I should note that I have made a few modifications to the example
file
because it wasn’t behaving as expected. Specifically, I disabled the
mmdebstgrap auto create because otherwise it was ignoring the tarball I had
created in the previous steps (including the apt-cacher-ng setting) and
creating a new tarball pulling straight from the internet at each build, at
each run of lintian, and at each run of piuparts. I also had to specify the
distribution or things didn’t work when building against a changelog that
targeting UNRELEASED.
Piuparts is fine if I let it generate its own tarball on each run. But it
doesn’t like using the tarball previously created.
# Set the chroot mode to be unshare.
$chroot_mode = 'unshare';
# Exit to a shell on command failures.
$external_commands = { "build-failed-commands" => [ [ '%SBUILD_SHELL' ] ] };
# Specify the distribution, -d
$distribution = 'unstable';
# Use an existing tarball instead of creating one each time.
$unshare_mmdebstrap_auto_create = 0;
## run lintian after every build (in the same chroot as the build): use --no-
run-lintian to override
$run_lintian = 1;
# pass any lintian options
$lintian_opts=['--info', '--display-info', '--verbose', '--fail-
on','error,warning'];
## run autopkgtest after every build (in a new, clean, chroot): use --no-run-
autopkgtest to override
$run_autopkgtest = 1;
# use 'unshare' for autopkgtests
$autopkgtest_root_args = [''];
$autopkgtest_opts = ['--apt-upgrade', '--', 'unshare', '--release', '%r', '--
arch', '%a' ];
## run piuparts after every build (in a new, clean, chroot): use --no-run-
piuparts to override
# this does not work in bookworm
$run_piuparts = 1;
$piuparts_root_args = ['PATH=/usr/sbin:/usr/bin', 'unshare', '--pid', '--

$piuparts_opts = ["--basetgz=$HOME/.cache/sbuild/%r-%a.tar.xz", '--no-
