In case you want to reproduce the failures, these are the rough steps I
used on Debian sid

1/ Install lxc

# apt install lxc

2/ Setup /etc/default/lxc-net:

# cat /etc/default/lxc-net
USE_LXC_BRIDGE="true"
LXC_BRIDGE="lxcbr0"
LXC_ADDR="10.0.3.1"
LXC_NETMASK="255.255.255.0"
LXC_NETWORK="10.0.3.0/24"
LXC_DHCP_RANGE="10.0.3.2,10.0.3.254"
LXC_DHCP_MAX="253"

# cat /etc/lxc/default.conf
lxc.network.type = veth
lxc.network.link = lxcbr0
lxc.network.flags = up

# systemctl restart lxc-net

3/ Install autopkgtest and create an LXC container for autopkgtest:

# apt install autopkgtest
# autopkgtest-build-lxc debian sid

4/ Clone the systemd trunk-ci scripts:

$ git clone https://salsa.debian.org/systemd-team/trunk-ci.git

5/ Create a dsc

$ ./make-dsc
<this will create a systemd_$version+upstream$date-0.master.dsc>

6/ Build the package using dpkg-buildpackage, pbuilder, sbuild, your
favourite tool.
You want to specify the "noudeb" profile, to speed up the build and
avoid building udebs.

7/ Run autopkgtest via LXC

# autopkgtest -o logs *.dsc *.deb -- lxc -s autopkgtest-sid


In case you want to run the LXC container with AA turned off, add the
following to /var/lib/lxc/autopkgtest-sid/config

lxc.aa_profile = unconfined

There are currently two, known failures with AA turned off:
- dnsmasq 2.80 introduced a regression in networkd-test.py
- test-bpf failing

With AA turned on, the list of failing tests is too long to list here.

I've made two runs of current systemd git master with AA turned on and
off. See
https://people.debian.org/~biebl/lxc/log-confined.txt
https://people.debian.org/~biebl/lxc/log-unconfined.txt

Hope this helpful.

Regards,
Michael
