[PATCH 0/4 branch usrmove] add ssh client module

[Dave Young]

Hi,

This is a ssh-client module for dracut. The first user could be kdump
because kdump need to scp vmcore to remote machine.

But It will benifit if it become an general module. Sometimes user need
an initrd which simply act as an emregency minimal ramdisk for test or
recovery use.

Currently it support both sshkey mode and interactive mode. With sshkey
mode user can precopy the key to remote machine and install sshkey to initrd.
With interactive mode user can drop into an emergency shell and ssh into
remote machine interactively.

For the interactive mode, due to there's no control tty for emergency shell,
so I add this feature based on Michal Soltys's "shell job control" patches, 

I rebased his patch to usrmove branch of Harald, post along with ssh patches

Thanks dave

Nitpick: why not call it "ssh" module instead of "ssh-client" module?

I will pick your patches into my tree, because:

1) So that we can test them as a whole
2) Both your patches and mine are mainly for kdump
3) Harald is on vacation these days

my tree is located at:

  git://github.com/congwang/dracut.git #kdump

Thanks.

ssh-client is better, maybe future there will be ssh-server come in.
In debian they are also two different packages.

Ok, makes sense, it is better to put this into the patch description.
