=head1 NAME

lxc-app-run - update configuration for an LXC application container

=head1 SYNOPSIS

    lxc-app-run [{-u|--user} <user>] [{-d|--dir|--directory} <directory>] \
        <container> <command> <parameters>...

=head1 ABSTRACT

main script used to run a previously configured LXC application container

Note that the script must be called as root (see L<App::LXC::Container::Run>
for details).

=head1 DESCRIPTION

This script runs a command inside of an LXC application container previously
created or updated with L<lxc-app-update>.  Parameters following the command
are passed through unmodified.  If no user is specified, the command runs as
C<root>, which is a root account especially restricted to the container
unless explicitly configured otherwise (usually a bad idea).  Likewise
another given user is restricted unless explicitly added to the list of
allowed users for the configuration (usually not a bad idea).  The command
is run in C</> or the specified directory.

Note that the previously created configuration for LXC itself contains a
mandatory C<MASTER> comment in the second line.  This comment may not be
deleted or modified, otherwise the start of the container may fail or the
container may not work as expected.
