add mdev.sh to hooks_lxc-mount.d

[asac]

To use this put a mdev.json in your platform folder, e.g. for a container named "busy" you could do:

cat busy/mdev.json 
{
    "rules": [
        "hwrng 0:0 666 \u003epv/",
        "ebbchar 0:0 666 \u003epv/",
        ".* 0:0 000 !"
    ]
}

thinking about appengine, are all these script going to work if stuff is no longer in /storage or in /lib/pv?

[asac]

whats the best practice here? IMO we should path an env that folks can use to find the 'step" dir? what do we provide such hooks so they can do the right thing in appengine and here?

[anibalportero]

If we could set those variables from pantavisor that would be great

[asac]

we need to inject then special envs in lxccontainer with the important paths so the hooks can refer to those VARs.

[asac]

lets add PV_STORAGE_DIR env

[asac]

lets discuss :)

Right now we use /storage as default for appengine. In the end is just about if we want to support a path different than /storage or if we want to support this feature in appengine too.
