autopkgtest-build-lxc - Create or update autopkgtest container for autopkgtest-virt-lxc


autopkgtest-build-lxc distribution release [architecture] [script]


autopkgtest-build-lxc creates or updates an LXC container autopkgtest- release which is suitable for autopkgtest's LXC runner autopkgtest-virt-lxc(1).
It calls lxc-create with the distribution template (which can currently be debian or ubuntu) and -rrelease to build a debootstrap-like container, then enables deb-src apt sources, and runs apt-get update.
It defaults to the native architecture, but you can specify a different one as third parameter.
The path to a script to be executed inside the container to customize the container can be passed as the fourth parameter. The script must be a POSIX shell script, and should not depend on bash-specific features.
If the container already exists, it updates it as unintrusively as possible by first creating a new temporary container, and then rsyncing its root file system back to the existing autopkgtest-release. Note that this could cause some side-effects and breakage if you have running containers with ephemeral overlays (i. e. using the --ephemeral option), but it does work in general. This update process does not interfere at all if you use autopkgtest-virt-lxc with cloning.
Note that you need to call this as root, unless you set up LXC to allow per-user containers. But user containers will not work with many or even most autopkgtests.
You can specify an apt proxy to use in the container in the $AUTOPKGTEST_APT_PROXY environment variable. If you have an apt proxy configured on the host, the container will automatically use this, otherwise there is no default.
