That is to make explicit the parameter name and to facilitate the 
parsing of the command line with getopt.

In some cases, the parsing of the command will be tricky:

lxc-start -n debian /sbin/myinit
=>
lxc-start debian /sbin/myinit

lxc-execute -n foo /bin/bash
=>
lxc-execute foo /bin/bash

lxc-cgroup -n foo cpuset.cpus 1
=>
lxc-cgroup foo cpuset.cpus 1

Yes I think so, with the -n option for backward compatibility (until the 
1.0.0 version is reached).

If you send the patches I will merge them after the 0.6.3 is out because 
I am consolidating this version right now.

Thanks
