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


       adt-build-lxc distribution release [architecture]


       adt-build-lxc  creates  or  updates  an  LXC  container  adt-release which is suitable for
       autopkgtest's LXC runner adt-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

       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  adt-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 adt-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 $ADT_APT_PROXY environment
       variable. If apt-cacher-ng is running on the local host, the container will  automatically
       use this (i. e. use the IP from the lxcbr0 interface) otherwise there is no default.
