<para>
+ When a container hook is executed, information is passed both
+ as command line arguments and through environment variables.
+ The arguments are:
+ <itemizedlist>
+ <listitem> Container name. </listitem>
+ <listitem> Section (always 'lxc'). </listitem>
+ <listitem> The hook type (i.e. 'clone' or 'pre-mount'). </listitem>
+ <listitem> Additional arguments In the
+ case of the clone hook, any extra arguments passed to
+ lxc-clone will appear as further arguments to the hook. </listitem>
+ </itemizedlist>
+ The following environment variables are set:
+ <itemizedlist>
+ <listitem> LXC_NAME: is the container's name. </listitem>
+ <listitem> LXC_ROOTFS_MOUNT: the path to the mounted root filesystem.
</listitem>
+ <listitem> LXC_CONFIG_FILE: the path to the container configuration
file. </listitem>
+ <listitem> LXC_SRC_NAME: in the case of the clone hook, this is the
original container's name. </listitem>
+ <listitem> LXC_ROOTFS_PATH: this is the lxc.rootfs enty for the
container. Note this is likely not where the mounted rootfs is to be found,
use LXC_ROOTFS_MOUNT for that. </listitem>
+ </itemizedlist>

Standard output from the hooks is logged at debug level.
Standard error is not logged, but can be captured by the
hook redirecting its standard error to standard output.
