Commit 7f12cae9 by Stéphane Graber
Options

Remove lxc-version, lxc-ps and lxc-netstat

lxc-ps and lxc-netstat have an unfortunate tendency to break every so often, produce mostly unreadable output and should be replaced by a lxc-attach call in 99% of the cases. In an effort to cleanup the lxc-* namespace, I think those two should go, so this patch gets rid of them as well as any reference to them in our documentation. I also think that lxc-version should disappear as it's only a one line shell script printing the version string, so having a whole command just for that seems to be a bit of a waste. Instead, this patch introduces a new --version common option which all binaries will automatically inherit and that'll print LXC_VERSION on stdout and exit 0.

<title>Description</title>
<para>
<command>lxc-ps</command> is a wrapper to the ps command
to report the name of lxc container associated
to reported processes.
</para>
<para>
The cgroup fs must be mounted before container creation,
to be able to have <command>lxc-ps</command> to find
the container associated to processes.
</para>
<para>
The additional specified <replaceable>ps options</replaceable> must not
remove the default ps header and the pid information,
to be able to have the <command>lxc-ps</command> to find
the container associated to processes.
