[Lxc-users] [PATCH 1/4] templates: consolidate and extend ubuntu templates

Serge Hallyn serge.hallyn at ubuntu.com
Fri Jun 24 00:41:24 UTC 2011


Consolidate lucid, maverick, natty, and oneiric templates into one 'ubuntu'
template.

Add support for specifying architecture.

Add support for '--trim|-x' option, which removes services like the lucid
template used to.  This creates smaller, faster-booting containers, but they
will not be safe with certain upgrades, like mountall or udev.  When -x is
not specified for lucid or maverick container, then install lxcguest from
the ubuntu-virt ppa, since it does not exist in the official archives, and
the container is not safe to boot without lxcguest.

Add support for '--bindhome <user>' option, which will cause /home/<user>
to be bind-mounted into the container, and create the user with his
original password, shell, and group memberships in the container.

changelog:
  june 23:
    lxc-ubuntu template: set lxc.arch in config
    install lxcguest when NOT trimming the container
    lxc-ubuntu: always install lxcguest in postprocess
